▼ In any automotive system, the tires play a very crucial role in defining both the safety and performance of the vehicle. The interaction between the tire and the road surface determines the vehicle's ability to accelerate, decelerate and steer. Having information about this interaction in real-time can be very valuable for the on-board advanced active safety systems to mitigate the risks ahead of time and keep the vehicle stable. The crucial information which can be obtained from the tire includes but are not limited to tire-road friction, tire forces (longitudinal, lateral), normal load, road surface characteristics and tire pressure. This information can be acquired through indirect vehicle dynamics based estimation algorithms or through direct measurements using sensors inside the tire. However, the indirect estimations fail to give an accurate measure of the vehicle state in certain conditions (e.g. side winds, road banking, surface change) and require ABS or VSC activation before the estimation begins. Therefore, to improve the performance of these active stability systems, direct measurement based approaches must be explored. This research expands the applications of Intelligent tire and focuses on using the sensor based measurement approach to develop estimation algorithms relating to tire force measurement. A tri-axial accelerometer is attached to the inner liner of the tire (Intelligent Tire) and two of such tires are placed on an instrumented (MSW, VBox, IMU, Encoders) VW Jetta. Different controlled tests are carried out on the instrumented vehicle and the Intelligent tire signal is analyzed to extract features related to the tire forces and pressure. Due to unavailability of direct force measurements at the wheel, a VW Jetta simulation model is developed in CarSim and the extracted features are validated with a good correlation.

▼ With the development of the computational technology, vehicle dynamics simulation has become a powerful tool for vehicle design in automotive industry nowadays. Since the tire plays a crucial role in vehicle handling, ride comfort, and durability, an accurate and efficient tire model becomes the prerequisite for the reliability and effectiveness of various vehicle dynamic simulations. In this dissertation, first an in-plane flexible ring tire model which is mainly used for straight line ride comfort and durability analysis is proposed. The model consists of a rigid rim, a certain number of discretized lumped mass belt points and massless tread blocks attached on the belt. Various virtual in-plane cleat tests according to the commercial ADAMS® FTire are conducted for parameter identification and validation of this in-plane tire model. The in-plane flexible ring tire model is further extended to a 3D out-of-plane tire model with a broader range of applications. The parameters in the 3D out-of-plane tire model are divided into in-plane tire parameters and out-of-plane tire parameters. Within the 3D tire model the values of the in-plane tire parameters are borrowed directly from the in-plane tire model, and the out-of-plane tire parameters are identified based on certain out-of-plane cleat tests. Various ADAMS® FTire driving/braking, cornering and cleat tests are conducted to validate the proposed 3D out-of-plane tire model. Besides, several important topics regarding to the flexible ring tire model, including the tire model efficiency, tire parameter sensitivity, robustness of the parameter identification procedure, and the relation between the tire parameters and tire model discretization, are also investigated in this dissertation.

▼ This thesis is a continuation of the model development work by Amir Gasmi in 2011 and Tim Lewis in 2012. The model was originally developed by Gasmi in 2011 to represent non-pneumatic tires. It centers on a thin, circular beam in contact with a rigid surface, which represents the belt package of the non-pneumatic tire. The beam is connected to a wheel with spokes. Gasmi developed a method to approximate these discrete spokes with a continuous load on the belt package. The results of this non-pneumatic tire model agreed very well with non-linear finite element analysis of a non-pneumatic tire. This model was adapted for pneumatic tires by Lewis in 2012. Lewis introduced a superposition scheme to reduce errors introduced by tension in the belts at the edge of contact. The sidewalls were approximated as circular in order to calculate sidewall stiffness. The results presented by Lewis for force versus deflection and counterdeflection agreed reasonably well with experimental measurements, but used stiffness values that were more from curve fitting than from a mechanics analysis of the tire geometry and material properties. The model presented in this thesis was developed directly from Lewis' model. This model includes more representative sidewall modeling based on membrane theory, and more representative belt properties based on composites theory. Unlike in the results presented by Lewis, the sidewall stiffness values (denoted as Kr and KÎ¸) are not considered to be inputs to the model; rather, the tire's geometrical design parameters (such as outer radius and sidewall width) are the inputs, and the stiffness values are calculated as part of the model. This allows for a more direct connection to tire design. The model has been improved to take into account a stiffness property called pre-tensioning, which allows the sidewalls (or in the case of a non-pneumatic tire, spokes) to maintain their stiffness in tension at small levels of negative deflection. This thesis will present a thorough investigation of the solutions with and without superposition, at a range of conditions. Also presented is an investigation of adjustments to input parameters to account for assumptions made in the model, as well as a sensitivity analysis.

▼ As vehicle dynamics research delves deeper into better insights in performance, modeling, and vehicle controls, one area remains of utmost importance: tire and road friction forces. The vehicle’s interaction with the road remains the dominant mean of vehicle control. Ultimately, the tire-road interaction will determine the majority of the vehicle’s capabilities and as the understanding of the interface improves, so too can the performance. With more computationally intensive systems being instrumented into modern vehicle systems, one is able to observe a great deal of important vehicle states directly for the remaining vehicle information; excellent estimation techniques are providing the rest of the insights. This study looks at the possible improvements that can be observed by implementing an adaptive dynamic tire model that is physical and flexible enough to permit time varying tire performance. The tire model selected is the Average Lumped LuGre Friction Tire Model, which was originally developed from physical properties of friction and tire systems. The material presented here examines the possibility of an adaptive tire model, which can be implemented on a real-time vehicle platform. The adaptive tire model is just one section of an entire control strategy that is being developed by General Motors in partnership with the University of Waterloo. The approach allows for estimated and measured vehicle information to provide input excitation for the tire model when driven with real-world conditions that enabling tire estimations. The tire model would then provide the controller information indicating the expected tire capacity and compares it with the instantaneous loading. The adaptive tire model has been tested with flat road experimental cases and the results provided reasonable estimates. The experimentation was performed with a fully instrumented research vehicle that used in-wheel force transducers, and later repeated with a completely different non-instrumented fully electric vehicle. The concepts and investigation presented here has initiated the ground work for a real-time implementation of a full adaptive tire model. Further work is still required to evaluate the influence of a range of operating conditions, tire pressure, and of different tire types. However, the findings indicate that this approach can produce reasonable results for the specified conditions examined.

▼ Expansive soils and stockpiled scrap tires present unique constructability and environmental challenges to the Front Range of Northern Colorado, respectively. Swell, stiffness and strength parameters of expansive soil-rubber (ESR) mixtures were systematically evaluated in the laboratory under one-dimensional and axisymmetric boundary conditions. ESR mixtures tested contained highly plastic, swelling clay from the Pierre shale formation and scrap tire rubber (STR) with nominal maximum particle sizes equal to approximately 6.7 or 19.0 mm. Compaction parameters were determined using standard Proctor compaction procedures (ASTM D698). Mixtures were compacted to relative compaction levels equal to 90, 95 or 100% and water contents varying by ± 2% around the optimum water content. Rubber contents used were equal to 0, 10 or 20%. Specimen and rubber particle sizes were also studied to assess differences in mechanical behavior of 6.7- and 19.0-mm ESR mixtures tested in one-dimensional compression employing three specimen sizes (small-scale, large-scale and field-scale) and in undrained axisymmetric compression employing two specimen sizes (small-scale and large-scale). Swell-compression results indicated the swell percent and swell pressure of specimens subjected to one-dimensional compression with lateral confinement were most impacted by initial water content, followed by relative compaction and rubber content. Compressibility parameters, including the constrained and elastic moduli, are most impacted by rubber content, followed by relative compaction and initial water content. Small-scale one-dimensional specimens demonstrated a minimal increase in swelling and insignificant variations in compressibility in comparison to large-scale one-dimensional and field-scale specimens. ESR specimens subjected to axisymmetric boundary conditions exhibited volumetric swell during flushing and back pressure saturation and swelling magnitudes were similar for nominal rubber particle sizes equal to 6.7 and 19.0 mm. Normal compression line parameters, λcs and κcs, were equal to 0.10 and 0.05, and 0.11 and 0.04 for large-scale 6.7- and 19.0-mm ESR specimens, respectively. Critical state parameters, Mcs, Γcs, and λcs, were equal to 1.20, 2.23 and 0.14, and 1.04, 2.15 and 0.13 for large-scale 6.7- and 19.0-mm ESR specimens, respectively. Scalability results indicate similar swell, stiffness and strength of ESR mixtures compacted to various specimen sizes with the inclusion of either 6.7- or 19.0-mm scrap tire rubber particles. Results indicate reasonable predictions of the mechanical behavior of ESR mixtures including tire chips can be made using conventional laboratory specimen sizes and testing techniques employing similar host expansive soils and rubber contents used to create ESR mixtures including granulated rubber.

▼ The pneumatic tire has been studied extensively since its invention in 1888. With the advent of high-powered computers and the use of the finite element method, the understanding of the tire's complex non-linear behavior has grown tremendously. However, one weakness of finite element models is that parameter studies are difficult and time consuming to perform. In contrast, an analytical model can quickly and easily perform extensive parameter studies. To the knowledge of the author, all existing analytical models of the tire make assumptions concerning the tire's behavior and construction that while useful for obtaining some of the first-order characteristics, are limited since they cannot relate tire behavior such as force-deflection to individual tire stiffnesses. As such, an adequate two-dimensional model of a pneumatic tire, including a finite element model, does not exist. Therefore, an analytical, two-dimensional model for a pneumatic tire in static contact with a rigid surface is developed and presented. The case of a non-pneumatic tire can be obtained as a special case. The quasi-static investigation concentrates on finding the relationships between the tire's size and stiffness and its deformation under loading. A total of seven stiffness parameters are accounted for. The belt of the tire is modeled using curved beam theory, developed by Gasmi, et al. (2011), which accounts for bending (EI), shearing (GA), and extensional (EA) deformations. The sidewall of the tire is modeled as a bi-linear spring (K_rT, K_rC) with pre-tensioning (F_P*) in the radial direction and a linear torsional spring (K_θ) in the circumferential direction. Application of virtual work leads to a set of 6th order differential equations for the displacements in the belt that must be solved in three distinct regions. The first region is the region where the radial deformation is greater than the radial deformation of the inflated and unloaded tire. The second region is the region where the radial deformation of the sidewall is less than the inflated position but not in contact with the ground, and the third region is defined to be the region in contact with the ground. The length of the contact patch is represented by the angle enclosed by the edges of contact, and analytical expressions of stress resultants and displacements at the centroids of cross-sections are expressed in terms of this angle. In order to improve the accuracy of the model for large deformations, a special inflation pressure was calculated that allowed the most accurate solution to the linear model to be obtained by minimizing the circumferential force in the region of the largest rotation of the curved beam. This solution was then modified to account for the true inflation pressure. This two-step solution procedure was validated with a geometrically nonlinear finite element model of a non-pneumatic tire. Force vs. deflection and force vs. counter deflection results were compared to experimental data for a… Advisors/Committee Members: Joseph, Paul F, Rhyne , Timothy B, Li , Gang.

Mašinsko inženjerstvo - Motorna vozila / Mechanical engineering - Motor vehicles

motornim vozilima“ razmatrane su mogućnosti unapređenja održavanja pneumatika na motornim vozilima. Opšti naučni cilj disertacije bio je razvoj metode modeliranja uticaja pritiska i opšteg stanja pneumatika na bezbednost saobraćaja, troškove pneumatika, troškove goriva i druge troškove eksploatacije vozila. Značajan cilj i doprinos rada je promocija proaktivnog pristupa održavanju pneumatika za komercijalna vozila a, s tim u vezi, i primena sistema za nadzor pritiska vazduha u pneumaticima (TPMS) kao konceptualnog rešenja koje je blisko konceptualnim rešenjima za ostale sisteme na vozilu, a koji su već poznati i u upotrebi. U okviru disertacije obavljena su istraživanja u SP „Lasta“ A.D., našem najvećem saobraćajnom preduzeću, sa ciljem da se utvrdi da li bi primena TPMS uređaja na komercijalnim vozilima, osim povećane bezbednosti, imala uticaja na povećanje ekonomičnosti eksploatacije. Istraživanja su obuhvatila utvrđivanje stanja pneumatika u SP „Lasta“ A.D., kontrolu i analizu pritisaka vazduha u pneumaticima u SP „Lasta“ A.D. i putna ispitivanja pneumatika u gradskom, prigradskom i međumesnom saobraćaju. Na osnovu analize rezultata istraživanja može se doneti zaključak da je sa gledišta bezbednosti saobraćaja, pogotovu kada se radi o prevozu putnika, održavanje propisanog pritiska vazduha od primarnog značaja. S obzirom da vozači tradicionalno izbegavaju svoje obaveze prema održavanju pneumatika proizvođači pneumatika i vozila izlaz iz ove situacije su potražili u novim tehničkim rešenjima. U doktorskoj disertaciji „Razvoj metodologije za proaktivno održavanje pneumatika na motornim vozilima“ je predstavljen model uticaja pneumatika na troškove eksploatacije vozila. Pošlo se od pretpostavke da odstupanje od propisanog pritiska vazduha u pneumatiku utiče na troškove eksploatacije vozila na četiri načina: povećava intenzitet habanja i smanjuje pređenu kilometražu između dva protektiranja, skraćuje vek spoljne gume, povećava potrošnju goriva (zbog povećanja otpora kotrljanja) i povećani broj iznenadnih otkaza usled separacije protektora ili eksplozije (usled preteranag zagrevanja pneumatika) . Za kvantifikaciju posledica neodgovarajućeg pritiska postavljene su odgovarajuće „krive zavisnosti“, odnosno krive korelacije između odstupanja pritiska od propisanog i promena u veku pneumatika, veku protektora i potrošnje goriva. „Krive zavisnosti“ su integrisane u zajednički model koji je iskorišćen za ocenu predloženih sistema za unapređenje održavanja pneumatika u SP „Lasta“ A.D...

▼ Discarded tires have been an environmental concern in different parts of the world. One mass application to avoid such environmental concern is to use them as embankment fill material in civil engineering projects. In such applications, discarded tires are usually used in a shred form referred as Tire Derived Aggregate (TDA). Tire derived aggregate has desirable properties for most civil engineering applications; it is lightweight, free-draining, and has good thermal resistivity. In the past, it has been successfully used as fill material in various engineering projects. Tire derived aggregate has also been used as fill material by mixing with soil. Despite the superior geotechnical characteristics and successful application, predicting settlement in the field based on laboratory tests has been a problem. Moreover, only TDA produced from Passenger and Light Truck Tire referred as PLTT has been used in the past. However, in regions with heavy industrial and mining activities, such as the Province of Alberta, Canada, Off-The-Road (OTR) tires have become a significant source for TDA production. The major challenge for the use of TDA from OTR is the lack of laboratory data or field experience. In this study, the application and engineering properties of TDA produced from PLTT and OTR, and PLTT-mixed with soil as fill material for highway embankment application has been investigated using large-scale laboratory or full-scale field experiments. The compression behavior of TDA, taking particle size and source of tire as experimental variable, has been investigated using large-scale laboratory testing apparatus. Based on results from the large-scale laboratory compression test, nonlinear elastic material model has been developed for TDA. The developed material model has been used in numerical analysis to predict settlement measured in the field for the construction of a test embankment. The result from numerical analysis agrees reasonable well with the measured settlement in the field. Various data were also collected from the field experiment where TDA or TDA-mixed with soil was used as fill material. The ease of construction for using TDA or TDA-mixed with soil as fill material, field mixing of TDA and soil, immediate and time-dependent settlement, potential for internal heating and overall performance have been evaluated from the data collected. Analyses of the field data support the use of PLTT, OTR, and TDA-mixed with soil as a fill material for highway embankment. The construction can be completed with conventional construction equipment and the performance is quite satisfactory. Moreover, such construction is beneficial to the environment by recycling a waste material.

▼ It has been shown that tire deformation can play an important role in the stability and handling of a bicycle. It is expected that an accurate understanding of tire behavior is necessary for correct understanding of rider behavior and that correct understanding of rider behavior is necessary for optimizing bicycle design. That certainly has been the case for motorcycles. Several instances of published bicycle tire stiffness data exist, but they seldom agree with each other, do not all measure the same properties, and often are missing key pieces of test configuration data, such as tire size, rim width, inflation pressure, or vertical load. In this project, three different test devices specific to bicycle tires were developed. Measured bicycle tire stiffnesses are presented for 14 different tires ranging from 22 to 50 mm wide, at inflation pressures from 2 to 11 bar (29 to 160 psi), under vertical loads from 304 to 731 Newtons (68 to 164 lb); for a total of about 120 different parameter combinations. Normalized cornering stiffness was found to vary from below 0.15 to over 0.35, which is ±40% from the average, and normalized camber stiffness varies from below 0.0075 to over 0.015, which is ±33% from the average. Based on numerical simulations, this is more than sufficient to influence bicycle stability and handling. Tires approach the camber stiffness necessary, without slip, for the net ground reaction force to be in the plane of the wheel, obeying the so-called tangent rule, but most tires with most inflation pressures and under most loads presented here fall below that. A numerical model, based on an analysis developed by Rotta for slender toroidal tire cross sections in contact with the ground, was also developed to provide insight into how the tires generated the forces they do and attempt to predict them from simpler measurements. Although actual values generated by the model do not exactly match measured values, the trends in contact patch size and lateral stiffness values generated do correspond well with measured data as parameters vary, such as inflation pressure, vertical load, and rim width.

▼ The research focuses on developing a methodology for modeling a pneumatic bias-ply tire with the finite element method for vehicle dynamics simulation. The tire as a load-carrying member in a vehicle system deserves emphasized formulation especially for the contact patch because its representation of mechanics in the contact patch directly impacts the handling and ride performance of a vehicle. On the other hand, the load transfer from the contact patch to the wheel hub is necessary for determining the inputs to a chassis. A finite element (FE) tire model has strong capability to handle these two issues. However, the high cost of computing resources restrains its application mainly in the tire design domain. This research aims to investigate how to balance the complexity of a simplified FE tire model without diminishing its capability towards representing the load transmission for vehicle dynamics simulation. The traditional FE tire model developed by tire suppliers usually consists of an extremely large number of elements, which makes it impossible to be included in a full-vehicle dynamics simulation. The material properties required by tire companies' FE tire models are protected. The car companies have an increasing need for a physical-based tire model to understand more about the interaction between the tire and chassis. A gap between the two sides occurs because the model used for tire design cannot directly help car companies for their purpose. All of these reasons motivate the current research to provide a solution to narrow this gap. Other modern tire models for vehicle dynamics, e.g. FTire or TAME, require a series of full-tire tests to calibrate their model parameters, which is expensive and time-consuming. One great merit of the proposed simplified FE tire model is that determining model inputs only requires small-scale specimen tests instead of full-tire tests. Because much of the usability of a model hinges on whether its input parameters are easily determined, this feature makes the current model low cost and easily accessible in the absence of proprietary information from the tire supplier. A Hoosier LC0 racing tire was selected as a proof of modeling concept. All modeling work was carried out using the general purpose commercial software Abaqus. The developed model was validated through static load-deflection test data together with Digital Image Correlation (DIC) data. The finite element models were further evaluated by predicting the traction/braking and cornering tire forces against Tire Test Consortium (TTC) data from the Calspan flat-track test facility. The emphasis was put on modeling techniques for the transient response due to the lack of available test data. The in-plane and out-of-plane performance of the Hoosier tire on the full-tire test data is used for model validation, not for "calibrating" the model. The agreement between model prediction and physical tests demonstrate the effectiveness of the proposed methodology. Advisors/Committee Members: West, Robert L. (committeechair), Ferris, John B.

▼ A differential steered, 13.6 kg robot was developed as an intelligent tire testing system and was used to investigate the potential of using piezoelectric film sensors in small tube-type pneumatic tires to characterize tire-ground interaction. One focus of recent research in the tire industry has been on instrumenting tires with sensors to monitor the tire, vehicle, or external environment. On small robots, tire sensors that measure the forces and deflections in the contact patch could be used to improve energy efficiency and/or mobility during a mission. The robot was assembled from a SuperDroid Robots kit and instrumented with low-cost piezoelectric film sensors from Measurement Specialties between the inner tube and the tire. An unlaminated and a laminated sensor were placed circumferentially along the tread and an unlaminated sensor was placed along the sidewall. A slip ring transferred the signals from the tire to the robot. There, the signal conditioning circuit extended the time constant of the sensors and filtered electromagnetic interference. The robot was tested with a controlled power sequence carried out on polished cement, ice, and sand at three power levels, two payload levels, and with two tire sizes. The results suggest that the sensors were capable of detecting normal pressure, deflection, and/or longitudinal strain. Added payload increased the amplitude of the signals for all sensors. On the smaller tires, sensors generally recorded a smaller, wider signal on sand compared to cement, indicating the potential to detect contact patch pressure and length. The signals recorded by the unlaminated sensor along the tread of the smaller tire were lower on ice compared to cement, indicating possible sensitivity to tractive force. Results were less consistent for the larger tires, possibly due to the large tread pattern.

▼ The vertical force generated from terrain-tire interaction has long been of interest for vehicle dynamic simulations and chassis development. As the terrain serves as the main excitation to the suspension system through pneumatic tire, proper terrain and tire models are required to produce reliable vehicle response. Due to the high complexity of the tire structure and the immense size of a high fidelity terrain profile, it is not efficient to calculate the terrain-tire interaction at every location. The use of a simpler tire model (e.g. point follower tire model) and a pre-filtered terrain profile as equivalent input will considerably reduce the simulation time. The desired produced responses would be nearly identical to the ones using a complex tire model and unfiltered terrain, with a significant computational efficiency improvement. In this work, a terrain pre-filtering technique is developed to improve simulation efficiency while still providing reliable load prediction. The work is divided into three parts. First a stochastic gridding method is developed to include the measurement uncertainties in the gridded terrain profile used as input to the vehicle simulation. The obtained uniformly spaced terrain is considered probabilistic, with a series of gridding nodes with heights represented by random variables. Next, a constraint mode tire model is proposed to emulate the tire radial displacement and the corresponding force given the terrain excitation. Finally, based on the constraint mode tire model, the pre-filtering technique is developed. At each location along the tire's path, the tire center height is adjusted until the spindle load reaches a pre-designated constant load. The resultant tire center trajectory is the pre-filtered terrain profile and serves as an equivalent input to the simple tire model. The vehicle response produced by using the pre-filtered terrain profile and the simple tire model is analyzed for accuracy assessment. The computational efficiency improvement is also examined. The effectiveness of the pre-filtering technique is validated on probabilistic terrain by using different realizations of terrain profiles. It is shown through multiple profiles that the computational efficiency can be improved by three orders of magnitude with no statistically significant change in resulting loading.

▼ Disposal costs of scrap tires have prompted researchers to investigate beneficial reuses for waste tires. One important application is use of tire chips as tire derived aggregate (TDA), which can be a substitute for rock aggregate in engineering applications. Properties of TDA were investigated through a series of experiments using type A TDA (maximum 8-in. length), type B TDA (maximum 12-in. length) and a 50/50 mixture of type A and type B TDA. Three areas of testing were completed on TDA, which included physical properties, substitution of rock aggregate with TDA in leach fields, and exothermic properties of TDA. A small and large magnitude dynamic vertical compression test was completed using tri-axial cylinders to measure the compressibility of TDA. Density, weight specific gravity, void ratio, and porosity were also calculated during experimental tests. During compression testing, TDA initially exhibited plastic compression under load, but after TDA was subjected to compressive loads it behaved like an elastic material. A constant-head permeameter, under loads up to 95 pounds per square inch, was used to measure the hydraulic conductivity of TDA. The hydraulic conductivity varied for all tests by TDA type (type A or B or a 50/50 mixture), applied pressure, and hydraulic gradient. Implications of substituting TDA for rock in leach fields were also investigated. Results indicated that TDA was a viable substitute for rock aggregate in septic systems with regards to wastewater treatment and durability. A leach field that contained TDA showed increased microbiological growth within the media and statistically significant effluent quality for eight constituents (of 84 tested constituents) when compared to a leach field containing rock aggregate that was under equivalent wastewater loading conditions. A thermal analysis of temperature changesover time was also completed using clean (did not have flammable liquids on the material) type A TDA in (1) a septic leach field, (2) a 20 ft. tall column of packed TDA, and (3) an underground earthen pit, where TDA was placed in the ground within 12 hours of manufacturing. In all thermal experiments, clean type A TDA did not show any hazardous reactions that would cause fire concerns. Advisors/Committee Members: Finney, Brad A..

Magistrantūros studijų baigiamajame darbe pateikiami padangų riedėjimo pasipriešinimo, lauko sąlygomis, tyrimo duomenys, esant skirtingiems atraminio paviršiaus tipams (pieva, ražiena, sausas žvyrkelis), įvairioms padangų vertikalioms apkrovoms (nuo 1,4 kN iki 5,9 kN) bei skirtingiems oro slėgiams padangoje (nuo 0,5 bar iki 2,0 bar). Darbo objektas – padangos riedėjimo pasipriešinimo koeficientas, jo reikšmės kitimas, esant skirtingiems padangos, apkrovos, ir atraminio paviršiaus parametrams. Tyrimas atliktas naudojant BELCHINA 7.50L – 16 ФБел – 253 padangą. Darbo metodai: padangos tyrimams atlikti buvo suprojektuotas ir pagamintas mobilus stendas, kuris buvo tvirtinamas prie savaeigės važiuoklės T–16M. Darbo rezultatai. Oro slėgis padangoje ir vertikalios apkrovos dydis turėjo įtakos riedėjimo pasipriešinimo koeficiento reikšmių kaitai, esant skirtingiems atraminiams paviršiams (pievoje, ražienoje, sausame žvyrkelyje). Mažinant padangos slėgį riedėjimo pasipriešinimo jėga yra tiesiogiai proporcinga vertikalios apkrovos jėgai ir atvirkščiai proporcinga slėgiui padangoje. Pievoje mažiausia riedėjimo pasipriešinimo jėgos Fp reikšmė gauta esant 1,0 bar slėgiui ir padangą apkrovus 1,4 kN vertikalia apkrova (Fp = 14,375 kN). Ražienoje – esant 0,5 bar slėgiui padangoje, ir 1,4 kN vertikaliai apkrovai (Fp = 22,283 kN).

The Master’s thesis presents findings of the study of tire rolling resistance under field conditions with different types of support surfaces (grassland, stubble, dry gravel-road), different vertical loads of tires (from 1.4 kN to 5.9 kN) and different air pressures in a tire (from 0.5 bar to 2.0 bar). Object of the thesis – tire rolling resistance coefficient f, change of its values with different parameters of a tire, load and support surface. The study was carried out using the tire BELCHINA 7.50L – 16 ФБел – 253. Methods of the thesis: in order to carry out the tire study, mobile stand was designed and manufactured and attached to self-propelled chassis T – 16M. Results of the thesis. Air pressure in the tire and the value of vertical load influenced the change of rolling resistance coefficient with different support surfaces (grassland, stubble, dry gravel-road). At the tire pressure being decreased, the rolling resistance force was directly proportional to the force of vertical load and is inversely proportional to pressure in the tire. The lowest value of rolling resistance force Fp on grassland was obtained at the pressure of 1,0 bar and vertical load of 1,4 kN on the tire (Fp = 14,375 kN). On stubble – at the pressure of 0,5 bar in the tire and vertical load of 1,4 kN (Fp = 22,283 kN). When the test was performed on dry gravel-road, the minimal value of rolling resistance force Fp was when the tire was affected by vertical load of 1,4 kN and air pressure in the tire...

▼ Significant time and cost savings can be realized through the use of virtual simulation of testing procedures across diverse areas of research and development. Fully detailed virtual truck models using the simplified off-road rigid-ring model parameters may further increase these economical savings within the automotive industry. The determination of the off-road rigid-ring parameters is meant to facilitate the simulation of full vehicle models developed by Volvo Group Trucks Technology. This works features new FEA (Finite Element Analysis) tire and SPH (Smoothed Particle Hydrodynamics) soil interaction modeling techniques. The in-plane and out-of-plane off-road rigid-ring parameters are predicted for an RHD (Regional Haul Drive) truck tire at varying operating conditions. The tire model is validated through static and dynamic virtual tests that are compared to previously published literature. Both the in-plane and out-of-plane off-road rigid-ring RHD parameters were successfully predicted. The majority of the in-plane parameters are strongly influenced by the inflation pressure of the tire because the in-plane parameters are derived with respect to the mode of vibration of the tire. The total equivalent vertical stiffness on a dry sand is not as heavily influenced by the inflation pressure compared to predictions on a hard surface. For perspective, at 110 psi, the dry sand total vertical stiffness is nearly nine times smaller than that determined on the hard surface, while the lateral stiffness on soft soil (Dry Sand) is at a minimal of three times higher than that of the corresponding values tested on a hard surface. The cornering stiffness is primarily load dependant because the inflation pressure is only noticeably influential at high vertical loads. More importantly, the soil builds in front of the tire, creating what is called a bulldozing effect, during high slip angles. The additional lateral force of the soil exerted onto the tire during cornering maneuvers may contribute to higher than expected results and may be confirmed through future investigation of the cohesion of the soil model.

▼ The objective of this study is to develop a high-fidelity physics-based flexible tire model that can be fully integrated into multibody dynamics computer algorithms for use in on-road and off-road vehicle dynamics simulation without ad-hoc co-simulation techniques. Despite the fact detailed finite element tire models using explicit finite element software have been widely utilized for structural design of tires by tire manufactures, it is recognized in the tire industry that existing state-of-the-art explicit finite element tire models are not capable of predicting the transient tire force characteristics accurately under severe vehicle maneuvering conditions due to the numerical instability that is essentially inevitable for explicit finite element procedures for severe loading scenarios and the lack of transient (dynamic) tire friction model suited for FE tire models. Furthermore, to integrate the deformable tire models into multibody full vehicle simulation, co-simulation technique could be an option for commercial software. However, there exist various challenges in co-simulation for the transient vehicle maneuvering simulation in terms of numerical stability and computational efficiency. The transient tire dynamics involves rapid changes in contact forces due to the abrupt braking and steering input, thus use of co-simulation requires very small step size to ensure the numerical stability and energy balance between two separate simulation using different solvers. In order to address these essential and challenging issues on the high-fidelity flexible tire model suited for multibody vehicle dynamics simulation, a physics-based tire model using the flexible multibody dynamics approach is proposed in this study. To this end, a continuum mechanics based shear deformable laminated composite shell element is developed based on the finite element absolute nodal coordinate formulation for modeling the complex fiber reinforced rubber tire structure. The assumed natural strain (ANS) and enhanced assumed strain (EAS) approaches are introduced for alleviating element lockings exhibited in the element. Use of the concept of the absolute nodal coordinate formulation leads to various advantages for tire dynamics simulation in that (1) constant mass matrix can be obtained for fully nonlinear dynamics simulation; (2) exact modeling of rigid body motion is ensured when strains are zero; and (3) non-incremental solution procedure utilized in the general multibody dynamics computer algorithm can be directly applied without specialized updating schemes for finite rotations. Using the proposed shear deformable laminated composite shell element, a physics-based flexible tire model is developed. To account for the transient tire friction characteristics including the friction-induced hysteresis that appears in severe maneuvering conditions, the distributed parameter LuGre tire friction model is integrated into the flexible tire model. To this end, the contact patch predicted by the structural tire model is discretized into… Advisors/Committee Members: Sugiyama, Hiroyuki, 1974- (supervisor).
