▼ The current state-of-the-art tyre models tend to be demanding in parameterisation terms, typically requiring extensive and expensive testing, and computational power. Consequently, an alternative parameterisation approach, which also allows for the separation of model fidelity from computational demand, is essential. Based on the above, a tyre model is introduced in this work. Tyre motion is separated into two components, the first being the non-linear global motion of the tyre as a rigid body and the second being the linear local deformation of each node. The resulting system of differential equations of motion consists of a reduced number of equations, depending on the number of rigid and elastic modes considered rather than the degrees of freedom. These equations are populated by the eigenvectors and the eigenvalues of the elastic tyre modes, the eigenvectors corresponding to the rigid tyre modes and the inertia properties of the tyre. The contact sub-model consists of bristles attached to each belt node. Shear forces generated in the contact area are calculated by a distributed LuGre friction model while vertical tread dynamics are obtained by the vertical motion of the contact nodes and the corresponding bristle stiffness and damping characteristics. To populate the abovementioned system of differential equations, the modal properties of the rigid and the elastic belt modes are required. In the context of the present work, rigid belt modes are calculated analytically, while in-plane and out-of-plane elastic belt modes are identified experimentally by performing modal testing on the physical tyre. To this end, the eigenvalue of any particular mode is obtained by fitting a rational fraction polynomial expression to frequency response data surrounding that mode. The eigenvector calculation requires a different approach as typically modes located in the vicinity of the examined mode have an effect on the apparent residue. Consequently, an alternative method has been developed which takes into account the out-of-band modes leading to identified residues representing only the modes of interest. The validation of the proposed modelling approach is performed by comparing simulation results to experimental data and trends found in the literature. In terms of vertical stiffness, correlation with experimental data is achieved for a limited vertical load range, due to the nature of the identified modal properties. Moreover, the tyre model response to transient lateral slip is investigated for a range of longitudinal speeds and vertical loads, and the resulting relaxation length trends are compared with the relevant literature.

▼ A lot of research has been done on the behaviour of pneumatic tyres and this has led to various tyre models and a lot of measurement data. However, in the specific field of bicycle tyres, not so much measurement data is available. However, in 2013 Andrew Dressel received the Degree of Doctor of Philosophy in Engineering at the University of Wisconsin-Milwaukee by presenting his research: Measuring and modeling the mechanical properties of bicycle tires. In this research he did a lot of measurements with multiple bicycle tyre brands and models under different conditions. The results from these measurements are interesting to use for modelling purposes. The goal of this research is to find out if it is possible to estimate the bicycle tyre behaviour in terms of vertical stiffness, cornering stiffness and camber stiffness based on known parameters like the inflation pressure, tyre width, rim width, vertical load and the rubber compound using a tyre model. An important part of this thesis are tyre models. The measurement data will be analysed using various tyre models. The first used tyre model is the brush model. This model uses a single material parameter and it turns out that this is too less to be able to extract clear relations between the tyre behaviour and the known parameters like inflation pressure, tyre width and rim width. The second tyre model that is used is the enhanced string model. This model is an extension of the brush model. This model has three material parameters for the vertical direction and also three material parameters for the lateral direction. Investigating this model shows that there is reasonable suspicion to assume that one of the model parameters represents the inflation pressure. In order to find the material parameters for every tyre, inflation pressure and normal load combination a parameter optimisation is required. The results from this parameter optimisation show that the suspected model parameter is actually not related to the inflation pressure. When the obtained model parameters from the optimisation are put back into the tyre model interesting results are acquired, because the model output agrees fairly well with the measurement data. This is unexpected because the model parameters were differing a lot depending on how they were obtained, e.g. obtaining the parameters from cornering stiffness or from camber stiffness. The answer to the research question is no. In order to extract relations between the model parameters and the tyres behaviour depending on their measurable properties, a lot more complete measurements are needed. The whole idea was to be able to estimate tyre behaviour without the need of extensive testing. This still might be possible, but in order to to that a lot more measurements are needed first. These measurements should create a baseline of model parameters which can be used to estimate the model parameters of unmeasured tyres.

▼ The main aim of the study was to operations strategy and sustainable competitive advantage in Tyre industry in Nairobi County, Kenya. The objectives of the study are: to determine the operation strategies used by Tyre Industry in Kenya; to determine the relationship between operations strategy and sustainable competitive advantage in Tyre Industry in Kenya and to determine challenges faced in implementation of sustainable competitive advantage by Tyre Industry in Kenya. The study was carried out through a survey where the unit of study was the Tyre Industry in Kenya. The study targeted 480 firms dealing with tyres in Nairobi County, Kenya as at September 2016. These firms include manufactures, distributers, wholesalers and retailer. The researcher adopted a stratified random sampling technique to select a sample size of 144 firms from the population 480 firms dealing with tyre. Primary data was obtained from one respondent in each firm in the Tyre industry in Kenya using a research questionnaire. This was drawn from top management. Both the primary and secondary data were used thus making qualitative and quantitate respectfully. From the findings on the operations strategies employed by tyre industries to remain competitive in the market, the study revealed the competitive strategies were: corporate strategy, customer-driven approach, core competencies, competitive priorities and development of product and service. The study revealed that the challenges faced by challenges faced Tyre Industry in Kenya in implementation of sustainable competitive advantage are; poor or vague strategy implementation, challenge of communication insemination, consumer protection and competition regulation, economic growth challenges (overall; by industry sector), lack of coordination and support from other levels of management and resistance from lower levels and lack of resources in the form of financial and human or indivisibility of resources. The researcher suggests that further research should be done on the challenges faced in adopting the sustainable competitive advantages hence hindering their effectiveness in response to increased Competition.

▼ The focus of the work in this thesis is concerned with the investigation and development of indirect measurement techniques. The methodology adopted is a combination of practical experimental, analytical deductive reasoning and simulation studies. This has led to proposals for a number of indirect tyre pressure monitoring systems, which are able to detect pressure loss under specific circumstances. The outcome overall is a proposal for a new supervisory system comprising of a modular framework, allowing various algorithms and techniques to be implemented in a complementary manner as they emerge and data sources become available. A number of contributions to the field have been made, which to the knowledge of the author, provide potential for further algorithm development and are imminently applicable given the above. The methods include a tyre pressure diagnosis via a wheel angular velocity comparator, the development of a model-based tyre pressure diagnosis via application of an unknown input observer and a parameter estimation scheme, a model-based tyre pressure diagnosis approach via an enhanced Kalman filter configured to estimate states including the input, a model-based tyre pressure diagnosis via cautious least squares, an investigation and critique of the effects of the choice of sampling interval on discrete-time models and estimation thereof. It is considered, that the extensive literature review provides a valuable historic insight into the tyre fault detection problem. It is clear, from the development and testing of the algorithms (and also the literature), that no single indirect pressure detection method is able to reliably detect changes in all driving scenarios which the regulations typically stipulate (depending on jurisdiction). In the absence of any information about the road input, the majority of the detection work must be shouldered by the wheel angular velocity comparator algorithm. As image recognition and sensor technology develops, it becomes possible to make estimates about the road surface and this removes some of the uncertainty on the input of the model-based parameter estimation approaches. Further work is detailed which goes some way towards realising the next steps in a development cycle suitable for a vehicle manufacturer to take through to the implementation stage.

▼ The tyre cavity resonance has been identified as a tonal noise that can be clearly heard inside the vehicle cabin which contributes to the increased level of annoyance. Tyre cavity resonance was analytically studied using impedance compact mobility matrix and statistical energy analysis. Both methods were then combined to form a hybrid analysis which is useful for a vibroacoustic system with material and manufacturing variations (such as tyre) in the mid-frequency range. Mid-frequency range is often defined as the range where they are too high for finite element analysis but too low for statistical energy analysis in order to obtain accurate results. The hybrid solution was shown to be advantageous to Monte Carlo method. The analytical results were supported by the results calculated from vibroacoustic software (VAOne), statistical energy analysis software (AutoSEA) and data from experimental modal tests as well as speaker-microphone response tests. Countermeasure using a multilayer trim attached onto the tyre inner surface was also presented. From the comparison between the analytical, finite element simulation and experimental data results, the tyre cavity resonance characteristics from the assumed physical model and actual tyre showed correlation to strong coupling condition. This study provides a better insight into the coupling condition of the tyre structure and cavity that could be used to understand and solve the problem. The described methods can also be applied to other geometrically similar structural-acoustic systems.

▼ The internal model is an important piece of the control system of an autonomous driving vehicle. In order for the model to deliver accurate predictions, a valid model structure and well chosen parameters are needed. Model parameters can be highly fluctuating or complex to predict, especially when looking into
tyre ground surface interaction models. Instead of predicting parameter values beforehand, they could be estimated and updated in real-time. Fluctuation or incorrectness can be adjusted while driving. However, this uncertainty in parameter value must be accounted for when applying control. Solving this problem by regarding the uncertainty in parameters of the internal vehicle model as a POMDP has been researched in this paper. The research question being: is it worthwhile to use the POMDP approach for online parameter estimation of autonomous passenger vehicles? To answer this multiple sub-questions have been composed. We start off looking into: what is the most suitable vehicle model? Different vehicle models and
tyre models were compared. Literature showed the bicycle model in combination with the linearized
tyre model to be most suitable for autonomous passenger vehicles. The next question is: What is the most promising algorithm? Using literature, suitable algorithms for solving this POMDP have been found and compared. From three compelling algorithms, the one best fitting the autonomous driving criteria was chosen. Knowing the model and the algorithm for the simulation the next question became: Does the algorithm perform on a vehicle model? To answer this question, the simulation has been implemented in MATLAB and performance has been tested. The results showed significant increase in parameter estimation performance. Within 2 timesteps the estimate had converged correctly. The next question is: Does the algorithm perform within realistic bounds? To answer this question, the same simulation as before has been used, but now with saturation on the steering input. This showed parameter estimation performance increase compared to the original trajectory, but not as overwhelming as without saturation. The next question is: Does the algorithm suffer from high noise? To answer this question, the same simulation has been used, but now with different levels of noise. The results showed parameter estimation performance significantly affected by increasing noise. The final sub-question is: Does the algorithm suit increasing model complexity? To answer this question, the amount of parameters have been increased in the simulation and there has been looked into the large matrices that accompany the algorithm. Results showed that increasing the complexity has a significant effect on the size of the simulation and algorithm matrices. In conclusion, from all of these experiments arose some very interesting results. This produced a useful insight into the strengths and weaknesses of the POMDP algorithm performing on a passenger vehicle, answering the research question. This also led to various recommendations for future…

▼ Autonomous Ground Vehicles (AGVs) are increasingly being used in more complex, harsh and remote environments because of their ability to replace a human driver, removing them from danger. However, the environments that are being targeted for the application of AGVs frequently occur in areas that have unstructured, uneven and non-uniform terrain. Safe and accurate navigation through such environments requires reliable terrain perception methods capable of identifying friction characteristics and an accurate system model, both are required in order to reduce the system uncertainties. Currently, methods for reducing these uncertainties are not well established.This thesis researched the sources of uncertainty that an AGV is
subject to whilst moving through an unstructured and non-uniform terrain. A number of key sources of uncertainty were identified, with changes in terrain type and thus the coefficient of friction being one key component, as well as the dynamic behaviour of the
tyre interacting with the terrain, especially during cornering maneuvers.Furthermore, it develops a novel terrain perception method which utilises purely non-semantic spatial information. The Extended Range Texture Analysis (ERTA) method is capable of providing an accurate terrain model that accounts for the identified terrain frictional and geometric characteristics, which reduces the uncertainties in terrain frictional characteristics that exists in the system model. The ERTA method can provide a solution for classifying the terrain types in an environment even in the absence of visual or semantic spatial features in a scene.Two novel
tyre models were also developed in this thesis: a simplified Friction Dependant
tyre model, and a 3D Analytical Dynamic
tyre model. The purpose of developing these models is to enable the incorporation of the sources of uncertainties, including both frictional characteristics provided by the terrain model and
tyre dynamic effects. The simulation results of both the developed
tyre models were compared against the widely accepted experimentally derived Magic Formula
tyre model.Following on from this research, control system designers can incorporate the developed
tyre models and perception method to reduce the uncertainties in the system parameters and disturbances to design significantly improved controllers.

▼ It is the
tyre that ensures the interaction between a wheel and road surface and it is the the
tyre which also acts as a primary cushioning. Its construction, features and condition highly influence driving properties of a car and thus passenger safety as well. In motorsports the
tyre is a key part of the vehicle and therefore it is necessary to make use of its complete potential for reaching the best results. The aim of this thesis is a device construction suitable for
tyre parameter and their characteristics measurement. The next task is to design a measuring system for
tyre pressure and temperature monitoring. With using of these devices a few real-
tyre measurements and subsequent result evaluation will be done. The output of the thesis is an overview of construction details, overview of selected
tyre parameters, design and drawing documentation of multipurpose measuring device and the results of my measurements.

▼ ENGLISH ABSTRACT: Waste tyres are proving to be a critical environmental and social problem not only in South Africa, but worldwide; with significant hazards associated with illegal dumping, stockpiling and burning. Efforts are currently directed towards the management of waste tyres, and pyrolysis is proving to be a promising form of waste
tyre recycling, with the production of potentially valuable products. Pyrolytic
tyre char, in particular, is a carbonaceous solid product originating from the carbon black filler within tyres, and constituting 40% of the total product mass produced by pyrolysis. Pyrolytic
tyre char, however, has an undesirable structure and is plagued by contaminants, thus considerably decreasing it value and market potential. Currently, South African waste
tyre pyrolysis plants are stockpiling great quantities of char, which reduces revenue and decreases investments. The problem statement was thus that the current char produced by waste
tyre pyrolysis is crude and has minimal market value or use which, in turn, reduces waste
tyre pyrolysis sustainability and waste
tyre recycling efforts.
A systematic approach was utilised, with a combination of literature research, experimentation, engineering design and economic evaluation methods employed to (i) investigate pyrolytic
tyre char upgrading methods and product opportunities; (ii) develop and propose a process for crude pyrolytic
tyre char upgrading; (iii) analyse the economic viability and appeal of the proposed crude pyrolytic
tyre char upgrading process.
A thorough literature review revealed that, utilising an acid-alkali leaching process, crude pyrolytic
tyre char could potentially be upgraded to a carbon black product. Industrial char and carbon black N330 were thus characterised to establish benchmark targets and process requirements, including ash content reduction from 16.24 to 1.95wt.%; BET surface area increase from 58.9m².g-¹ to 80.22m².g-¹; and average particle size reduction from 153.2 to 38.5μm. Furthermore, a mineralogical study revealed the ash contained approximately half silicon/silicon dioxide and half metallic components; thus substantiating the use of both an acid and an alkali.
Acids and alkalis mentioned in literature, with regards to pyrolytic
tyre char demineralisation, were screened as per demineralisation ability and raw material costs. Hydrochloric acid and sodium hydroxide proved to be superior. Subsequently, significant process factors, including extraction time, extraction temperature and lixiviant concentration, were analysed through kinetic trials and sequential extractions. A final acid-alkali demineralisation process was thus established; and pyrolytic
tyre char was upgraded to a carbon black product using 3x 5.0M NaOH washes at 88°C for 60minutes followed by 1x 1.0M hydrochloric wash at 80°C for 20minutes, including water washes prior to each lixiviant wash. Additionally, 100g lixiviant was utilised per wash; with the char: lixiviant ratio decreasing from an initial 20:100 (g/g).
The upgraded pyrolytic
tyre…

▼ Several types of discrepancies have been examined between CFD simulations, wind tunnel measurements and real world conditions. The results of different wheel rotation methods show that while stationary approaches can often substitute real unsteady wheel rotation, they can also be very sensitive to the exact angular positioning of wheel rims. Using both measured and computed flow fields, the lower part of wheel wake was identified as a key area, showing differences between rotation methods and sources of simulation errors in general. It was also shown that the level of detail in
tyre geometry and its deformation near contact patch do not have a large impact on accuracy. Due to the absence of
tyre rotation, the
tyre sidewall was identified as an important place of flow separation with large effect on flow field and forces. Angle of attack study confirmed that assessing purely straight-line drag causes its under prediction compared to real-world values. This judgement would however benefit from obtaining data in more adverse conditions compared to those currently available. Finally,
tyre radial expansion was investigated, causing a drop in drag with increasing vehicle velocity and altering the flow around the rear bodywork. Ignoring this effect can therefore negatively influence the aerodynamic development of a vehicle.

▼ This research is concerned with the strength
deflection ductility and durability investigation of a new
innovative construction material named as Tyre Rubber Aggregate
Concrete TRAC TRAC is a concrete made of partial replacement of
waste tyre rubber aggregates for natural aggregates Rubber
aggregates are obtained by reduction of scrap tyres to aggregate
sizes using mechanical grinding or by chiseling in to required
dimensions An experimental investigation is carried out to identify
the potential of incorporating rubber aggregates as a partial
replacement of fine and coarse aggregate in the concrete using
weigh batching method Numerous tests are conducted on fresh and
hardened state of TRAC such as workability compressive strength
split tensile strength and flexural strength The results showed
that the compressive strength decreases when the percentage of
replacement of rubber aggregate increases

▼ For a
tyre manufacturing company to compete nationally and internationally, the maximum utilization of their equipment is extremely important. Thus, having a maintenance system in place that will ensure this will be essential. In today’s competitive environment, the need to go further than just scheduling maintenance in accordance with manufacturer’s recommendations as a method of improving productivity and product quality was quickly recognized by those companies who were committed to total quality management programmes. The objective of this study was to propose an appropriate strategy for the implementation of Total Productive Maintenance at Continental
Tyre South Africa. To achieve this, the current Total Productive Maintenance (TPM) programme, in the steel stock preparation division in affiliated Continental plants in Otrokovice in the Czech Republic and Puchov in the Slovak Republic was evaluated. A comprehensive literature study was performed on Total Productive Maintenance programmes. A questionnaire was designed based on the guidelines in the literature study in order to establish the effectiveness of implemented TPM programmes. The researcher used the random sampling method of selection and distributed the questionnaire to 62 potential respondents via hand-outs from each plant’s respective heads of departments. 56 completed questionnaires were returned and these were processed and analyzed using Microsoft Office Excel 2003, running on the Windows XP suite of computer packages. The opinions of the various respondents were compared with the guidelines provided in the literature survey, in order to identify how to answer two main questions the author wanted to use as part of selecting an appropriate implementation approach for TPM at Continental
Tyre South Africa. These were: • How much are the employees involved and empowered to perform their TPM tasks?; and • How effective is the implemented TPM programme? The following were the main recommendations and conclusions: • The experiences gained by plants like Otrokovice and Puchov must be used as a guideline for introduction and implementation; • The employees that will be required to perform the TPM tasks must be properly trained and they should receive the necessary tools to perform their tasks; • It is essential that everyone throughout the entire manufacturing organization is involved from the start in the development, improvement and maintenance of the TPM programme and that the driving force behind it should be a combination of maintenance, production and quality; and • TPM will achieve it’s objectives if: • The equipment effectiveness can be improved; • Autonomous maintenance is achieved; • Planned maintenance is in place; • Staff are trained in relevant maintenance skills; and • Early equipment management can be achieved

▼ Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2]. Numerous toxicological researches highlight that Carbon black may act as a universal carrier of wide variety of chemicals of varying toxicity to the human body [3,4]. Consequently, researcher endeavours in finding sustainable and eco-friendlier alternatives. The aim of this thesis was to further investigate the possibilities of replacing carbon black with modified lignin in rubber elastomeric materials- for the development of sustainable tyre technology. The research questions for this thesis were divided in four parts: How does lignin (unmodified and modified) structure affect the mechanical properties of the rubber compound?How does lignin affect the cross-link and vulcanisation of the rubber compound?How does lignin affect the dispersion of the rubber compound?Which modification of lignin is more compatible with the rubber compound? Lignin is the second most abundant biopolymer on earth (after cellulose) and is mainly extracted from black liquor, which is obtained as a by-product from the pulp- and paper. In this study, pure lignin was obtained from Lignoboost process (Lignocity) and underwent an esterification process of aldehydes (1. Protonic, 2. Butyric, 3. Isobutyric 4. Methacrylic and 5. Crotonic). LignoCity 2.0 is a project focusing on the development of sustainable products and processes connected to lignin. The structure of the modified lignin was characterized using a FTIR-spectra. Furthermore, seven different rubber compounds were produced at Anva Poly Tech, which is a company that manufactures rubber materials in Sunne, Sweden. The mechanical testing involved: Tensile strength, IRHD, Hardness, Rebound Resilience and Rheometer curve. It was observable that the addition of lignin in rubber compounds did not significantly improve the mechanical properties compared to conventional carbon black. However, the rheometer curves of the lignin samples clearly indicate an increase in scorch time and that lignin takes part in the vulcanization process, thus the delay in crosslinking phase. In addition, it was visible that the fully replacement of carbon black with lignin (unmodified and modified) increased the elongation at break. Furthermore, the FTIR spectra indicated a complete and successful modification of lignin. In addition, compared to unmodified lignin, it was visible that the modified lignin significantly improved the mechanical properties. Therefore, it was possible to conclude that the configuration and double bonds of the aldehydes had an impact on the vulcanization process. Butyric and isobutyric lignin were the better choices compared to the other lignin…

▼ The system for predicting tyre performance on sand, measuring sand strength with a cone penetrometer and using non-dimensional empirical curves developed by the Waterways Experiment Station (WES) of the U. S. Army was investigated. A series of tyre tests on dry Cresswell sand were carried out and the results were in complete disagreement with the WES system, in both its original and revised forms. It was therefore decided to try to discover the basic soil mechanics of such a system and modify it accordingly. Critical State Soil Mechanics describes two types of soil behaviour, dilating and weakening or compacting and strengthening. It was found that the first of these processes occurred in most situations likely to be found naturally, compaction occurring only in the loosest states obtainable under laboratory conditions. Under dilating conditions sand strength is described by the density, γ (Gamma). and the angle of internal friction, Ø. The angle of friction, for a single sand, was found to vary over a very wide range, depending on the state of compaction and the confining pressure. Density does not vary greatly. The cone penetrometer gradient, G, was found to be related to Ø at a low confining pressure, and the relationship was well described by the theory of Durgunoglu and Mitchell (1975). This lead to the idea that tractive performance would be dependent on Ø, which would be lower the higher the tyre contact pressure. A series of tyre tests on a single tyre on two sands showed clearly that performance depended on both tyre pressure and tyre load. The WES numeric only contains pressure. It was therefore decided to include both parameters by expressing performance by several curves depending on the tyre deflection. Deflection. being expressed as a ratio of tyre diameter rather than tyre section height. The new system was shown to describe all of the WES data better and more logically than their system. The reason why the system cannot describe performance in Yuma and Mortar sands with the same single curve as for Leighton Buzzard and Cresswell remains a mystery.

▼ This work addresses the problem of tyre tread pattern design for optimum wet grip performance. A mathematical model of tyre behaviour on wet roads has been developed. This utilizes the finite element method in the representation of tread pattern geometry. The performance of a particular tread pattern is found in terms of the fluid pressures and film thicknesses existing within the contact patch, under wet conditions. Many modern tread patterns are based on 'blocks', and a computer model has been developed specifically to assist the tyre designer in the design of these blocks for improved wet grip. Numerical results are presented both for complete contact patches and for individual tread blocks. To allow the use of the computer models by the tyre designer, with no specialist knowledge of the finite element method, special purpose mesh generation and plotting programs have been developed. Experiments have been undertaken whereby the fluid pressures and film thicknesses existing in the tyre contact patch have been measured under high speed conditions in the wet. These measure- ments were made on an indoor testing machine, and the techniques developed can be used in the routine evaluation of tyre wet grip performance. Some results of experiments performed on plain and simple patterned tyres are presented. The main purpose of this work was the development of the mathematical models which can be used for future research into, and design of, tyres for improved wet grip. However, some conclusions are made as to possible features which could be utilized in future tyre designs.

▼ This thesis introduces a versatile finite element package, which is tailored for the static and dynamic analysis of radial tyres. A new axisymmetric solid-of-revolution element which takes into consideration, large deformation, the influence of composite orthotropic material and the viscoelasticity and the nonlinearity of the material properties, has been developed for a general loaded tyre. The finite element package has been verified by comparing its results with available analytical, numerical and experimental results. A full static and dynamic investigation has been carried out for a commercial tyre 175 HR 14 and results obtained by using the package have been compared with available experimental results developed by DUNLOP or carried out at Cranfieid. The package has proved to be reliable, flexible, efficient, economic and accurate. The numerical instability problems which are prevalent in this type of analysis have been overcome by the derivation of a developed Newton-Raphson iterative scheme.

▼ The aim of the research described in this thesis is to assess the technical feasibility of pneumatic tyres for passenger cars which have no directional reinforcement in their carcasses. Conventional tyres are constructed from composites of twisted textile or steel cords in a rubber matrix, a process which is both labour intensive and costly. If it were possible to injection mould or cast tyre carcasses in a single operation, and if the performance of the resulting tyres matched that of modern radial ply tyres, then the implications for the tyre industry would be of major proportions. After reviewing the history of pneumatic tyres and summarising their principal attributes, the design of unreinforced or fabricless tyres is investigated and methods developed for defining their meridional profiles. Materials suitable for their carcasses and treads are then considered, prior to describing the manufacture of two series of tyres designed to have section height to width ratios, or aspect ratios, of 0.9 and 0.7 respectively. To facilitate experimental work, two sizes of tyres were employed: half scale models for which testing procQdures had been developed previously; and a size suitable for small saloon cars. The results obtained on a range of tyre properties are presented and analysed to give a number of empirical relationships between the properties and the design variables: carcass material Young's modulus, carcass wall thickness and the inflation pressure. For the important property of radial stiffness which affects other tyre characteristics, an improved method of analysis is developed to allow the structural and pneumatic components to be quantified. Using the relationships established experimentally, consideration is given to optimising the design of a fabricless tyre. It is concluded that to approach the performance of a conventional tyre, a design with a low aspect ratio is preferred but, to restrict growth with inflation'pressure, limited directional reinforcement must be included as a circumferential-belt beneath the tread. Nevertheless, the discussion concludes that there are fundamental reasons why even the optimised tyre would be unacceptable for use on modern passenger cars, although less demanding applications may be identified.

▼ As circuit testing days are expensive and limited by regulations, racing teams are more and more dependent on simulation tools. Van Amersfoort Racing built their own racing simulator to train drivers in an fully controlled environment. This environment is based on commercially available simulation software rFactor. However, no research on the accuracy of the physics of this software is available. Since level of fidelity of race simulators is important for the perception of racing drivers, force feedback steering forces are analyzed. Information of the real Formula 3 car is used to upgrade the vehicle model used in rFactor and to develop a Multibody Dynamic vehicle model of the same car. Steering metrics are used to make qualitative comparisons between steering force measurement in the real car, the simulator and the Multibody Dynamic model. It is shown that the baseline simulator vehicle model is less sensitive to steering input compared to the real car. Furthermore the simulator driver theoretically senses higher steering torques for a given lateral acceleration discarding electric power limitations of the force feedback motor. As a desire to improve simulator fidelity, a Pacejka tyre model of the Hankook Formula 3 tyre is converted to an rFactor model together with an improved suspension model using the exact suspension geometry as provided by car manufacturer Dallara. Simultaneously, the Multibody Dynamic vehicle model is constructed from these submodels, which purely focusses on lateral dynamics. In order to use the lateral based Multibody Dynamic model as a tool for simulation and assessment, its response is tested given the same input as the real Formula 3 car experienced during a particular test. Three cases are considered: weaving on a straight, a low speed corner and a high speed corner. Longitudinal load transfer is inherent in low speed corners, which, due to its limitation in the Multibody Dynamic model, leaves the model adjustments inconclusive. Furthermore, tyre relaxation plays an important role in low speed corners following each other up in a short period of time, which affect low speed steering metrics. The Multibody Dynamic model showed close correlation of steering metrics with real car measurements for the high speed corner. The updated rFactor model improved steering torque feedback despite higher required steering angles.

▼ The tyre is an essential part of a road vehicle. It is in the contact between road and tyre that the forces that create the possibility for the driver to control the vehicle are generated. Tyres, however, wear down, which leads to both unhealthy wear particles and disposal of old tyres, both of which are harmful to the environment. If one could learn more about what causes wear, it might be possible to reduce tyre wear, which would be beneficial from both an economic and an ecological point of view. The aim of this thesis work is to develop a tyre model that can simulate tyre wear and take temperature, pressure and vehicle settings into account. Based on tyre brush theory, a tyre wear model has been developed which includes a thermal model, a pressure model and a friction model. Simulations and analysis of different cases has been performed. From the results, one can conclude the following: the tyre temperature and inflation pressure change with the distance the vehicle travels at the beginning and later become steady; higher external temperature will decrease tyre wear rate since the inflation pressure increases with the external temperature and the sliding friction decreases; higher vehicle speed leads to a higher tyre wear rate; the tyre temperature increases with increasing vehicle speed; the amount of tyre wear increases linearly with the normal load on the tyre; the tyre wear increases with the slip ratio exponentially due to both the siding distance and the sliding friction increasing with the slip ratio; the tyre wear increases exponentially with the slip angle. The complete model can estimate the tyre wear with different vehicle settings and external factors. More experiments are needed in the future to validate the complete model. In addition, since the heat transfer coefficient is changeable with temperature, the thermal model can be improved by introducing dynamic heat transfer coefficients. The Savkoor friction model used in the report can also be improved by tuning its parameters using more experimental data.

▼ Vehicle dynamic simulations form a significant part of
the design and development process of vehicles. These simulations
are used to study and improve the vehicle’s durability, ride
comfort and handling capabilities. All forces acting on the vehicle
are either generated in the
tyre-road interface or are due to
aerodynamic effects, where at low speeds the latter one can be
ignored. The accuracy of the
tyre model describing the forces on
the
tyre-road interface is thus of exceptional importance. It
ensures that the simulation model is an accurate representation of
the actual vehicle.
Various approaches are adopted when developing
mathematical
tyre models. Many of these models are developed to
study the handling capabilities of passenger cars over a smooth
road. Passenger car tyres are the focal point as larger tyres
introduce some difficulties due to their size and load rating.
Off-road truck tyres also differ in their construction which will
influence force and moment generation of the
tyre. Research efforts
are increasing to meet the need of
tyre models that can describe
the behaviour of the
tyre over uneven terrain with sufficient
accuracy. This thesis addresses the question of whether existing
mathematical
tyre models can accurately describe the forces and
moments generated by a large off-road
tyre while driving over rough
terrain.
The complexity of different mathematical
tyre models
varies greatly, as does the parameterisation efforts required to
obtain the model parameters. The parameterization of most
tyre
models relies on some experimental test data that is used to
extract the necessary information to fit model parameters. The
selection of a suitable
tyre model for a simulation is often
dependent on the availability of such experimental data and the
effort to identify the required parameters. In this study the
parameterisation process for four different
tyre models, are
discussed in detail to highlight the difficulties in acquiring the
test data and the effort to parameterize the model. The models
considered are the One Point Contact, 3D Equivalent Volume contact,
3D Enveloping Contact and FTire model.
Experimental measurements
are conducted on a 16.00R20 Michelin XZL
tyre. Laboratory tests, as
well as field tests, over discrete obstacles and uneven hard
surfaces are used for parameterisation and validation purposes.
Simulation results are compared to experimental test data to
determine whether the models could be used to describe the
tyre
road interactions with sufficient accuracy. Recommendations are
made for
tyre model selection and model accuracy for simulations
over rough off-road surfaces.

▼ A successful model for off-road tyres must be reliable, efficient and capable of reproducing and predicting the main system phenomena. Mathematical models are proposed for longitudinal, lateral and combined lateral and longitudinal force generation characteristics of off-road tyres. For a better understanding of off-road tyre behaviour, the study of the interaction between the tyre forces and those generated by the deformed soil is very important. Details of the force system in the contact patch, therefore, are used as a basis for developing models for the prediction of the tractive performance and comering characteristics of off-road tyres. Previous work of the relevant literature pertaining to tyre behaviour is reviewed to provide the reader with background information on off-road tyre characteristics. Various models for off-road tyres of differing degrees of complexity but which all incorporate the key features of off-road tyre problems are then developed. Previous methods of analysing the combined lateral and longitudinal forces generated by off-road tyres on deformable surfaces are investigated. A modified version of a previous model is then proposed which is based on a different and original method for investigating tyre behaviour in the contact region. An entirely new model is then developed which is based on a modification of the "multi-spoke" tyre model used for road vehicle studies. Predicted results are compared with those obtained from other models and with reported experimental data. The usefulness of such models is in problems involving the steering, braking and handling behaviour of off-road vehicles. Hence, the models are formulated so that they can be applied to such vehicle problems by enabling lateral and longitudinal forces on the tyre to be predicted from any combined conditions of wheelslip, wheelskid and slip angle. The proposed models provide an improved qualitative description of behaviour in the contact region. Although slightly more complex than previous models, the computational load is nevertheless sufficiently small that the tyre models can conveniently be incorporated in off-road vehicle handling models. Suggestions for future recommendations are discussed with particular reference to improving the predictive models and for a possible extension of the study to generate more detailed practical results for tyre forces under controlled experimental conditions.

▼ The in-plane phenomena of interaction between the tyre structural response and contact force generation are investigated in this work. The challenges of the physical tyre simulation are identified, primarily associated with the computational load imposed by the need to capture the space distributed mechanisms that prescribe the above interaction. The method of modal expansion and reduction is proposed for the moderation of this load. The theoretical framework for the transformation of a tyre modal representation into a transient contact and shear force generation model is developed. Various modelling approaches are examined with regards to their modal prediction characteristics. Linear and non linear structural features as well as the physical properties that define the broad range modal behaviour are identified. A discretised form of the ring model is derived and combined with a foundation of viscoelastic tread elements for simulating the transient contact behaviour of the tyre. The resulting pattern of the modes' excitation justifies the validity of the modal reduction method and reveals the relative importance of various mechanisms and physical properties in tyre contact behaviour. The interaction between the friction controlled shear slip of the tread, the belt compliance and the sidewall buckling is found to be reflected on the two-dimensional contact pressure distribution patterns. A method able to simulate the dynamic transient rolling and slipping operating conditions is developed, although the small displacement assumption of the modal approach is dropped. The method, which is based on the combined modal-time and space-time domain solutions, is applied on the study of the physical mechanism of the launch process. The examination of the model under steady state kinematic conditions reveals the saturation of the traction force for profound levels of slip, which highlights the contribution of the structural mechanisms on the macroscopically observed shear force performance of the tyre. The variation of the modes' level of excitation, as induced by the operating conditions, is proposed for the capture of the physical properties effect on tyre behaviour and performance.

▼ Long combination vehicles are the future of road transportation. They have much
better energy and transport efficiency compared to traditional transport vehicles.
There is a huge interest in using long combination vehicles for transporting goods
in Sweden. In Finland, long combination vehicles (34.5 m, 76 ton) were introduced
to the roads in the end of January 2019.
In Sweden, performance based standards, or PBSs, are becoming an accepted tool
for evaluating LCV’s safety and transport efficiency. The goal of this thesis is to produce the simplest possible vehicle models, for the performance based
standards that concern lateral dynamics. These models will be used to evaluate
those performance based standards, with a minimum number of parameters. The
models should include lateral dynamics, roll dynamics due to high load and tyre
relaxation. Non-linear tyre model will also be implemented to the simulation
models. In simulations, single lane change manoeuvre was used to evaluate the
performance of the created vehicle models.
The finalized models were validated against high-fidelity models from Volvo GTT.
The models were created in Modelica language and implemented to OpenPBS
library.

▼ The worlds crude steel production has seen a progressive growth from about 595 million tons in 1970 to 1527 million tons in 2011. This progressive growth, often attributed to the recovery of South East Asia from the economic and financial recession in 1998, has been accompanied by an equally progressive shift from the BOF to EAF as the mode of production of crude steel. The shift from the BOF to EAF has often been attributed to the latters low capital and operating cost coupled with its flexibility in the use of scrap. Accordingly, the demand for high quality scrap has soared, almost to the point of being scarce in most steel producing countries, a situation that calls for the development of novel technologies to produce alternative iron materials (AI) to supplement scrap in EAF steelmaking. Such novel technologies must not only be affordable from the economic point of view, they must also be environmentally benign in order to be able to meet the stiff national and international legislations on the environment. Anthracite and metallurgical coke are the conventional materials used for reduction of iron oxides and slag foaming in EAF steelmaking. In order to address the issues of cost, availability and restrictions on greenhouse gas emissions, alternative carbon sources are required to replace, at least partially, these conventional materials. Postconsumer plastics like polyethylene and end-of-life tyres (ELTs) contain both carbon and hydrogen, which are known reductants for iron oxide reduction. In the present study, the reduction of EAF slags containing FeO by metallurgical coke (Met Coke), high density polyethylene (HDPE), rubber
tyre (RT), polyethylene terephthalate (PET) and different blends of coke with the three polymers was investigated. The potential feasibility of utilising these polymers as reducing agents along with the kinetics of the reaction forms the central theme.Composite pellets were formed from EAF slags (47.1% FeO) and different blends of coke-polymer carbonaceous materials and were heated rapidly under inert environment (1 l/min argon) in a horizontal resistance tube furnace at four different temperatures 1450, 1500, 1550 and 1600 °C. The off gas produced from the reaction was analysed continuously by an infrared gas analyser attached to the system to monitor CO, CO2 and CH4 gases produced by the reduction reaction and the results were recorded in a data-logging computer. The rate and extent of reaction were calculated based on a mass balance for oxygen removal from the iron oxide and the content of reduced iron metal was determined by the following chemical analysis methods: LECO C/S analysis for its C and S contents and LECO Oxygen analyser for its O content.The gas phase interactions showed a reactive coke-polymer carbonaceous blend characterised by an improved generation of gaseous reducing species (H2, CO, CH4) in the furnace environment. The CO emissions from metallurgical coke showed lower concentrations in comparison to those from the Coke-polymer blends; however, the CO2…

▼ Nowadays virtual prototyping tools play an important part in the development of vehicles. For studying the dynamics of a vehicle, complex vehicle models are required that are composed of several accurately modelled components. As the
tyre constitutes the only contact between the vehicle and the road surface, it is one of the most important components of a vehicle model. For performing ride comfort and durability analyses, there is a need for accurate
tyre models that can predict the loads that are transmitted from the
tyre to the wheel axle when driving over road irregularities. In this study, such a
tyre simulation model is developed that can represent the dynamic response of a
tyre when rolling over uneven road surfaces. The approach followed is the combination of the well-known rigid ring dynamic
tyre model and a suitable enveloping model that generates a three-dimensional effective road surface, which is used as input for the rigid ring model. The thesis deals with the development of the enveloping models and with the extension of the rigid ring
tyre model so that this model is capable of handling the effective road surface. It is shown that the combination of the rigid ring model and the enveloping model can be used successfully to describe the
tyre dynamic response to uneven road surfaces. In this research project, numerous experiments have been carried out for model development, parameter identification and model validation. The results of many of these experiments are presented in the thesis.
