▼ High-Speed Rail (HSR) as a fast, reliable and environmentally friendly mode of transportation has received a lot of attention in recent decades. The International Union of Railways reported that there are more than 18600 miles of HSR in operation and about 1.6 billion passengers per year are carried by them. Although there are plans for HSR in many states including Florida, the United States, however, is still hesitant to develop its own HSR network. One of the main barriers to developing high-speed rail is excessive vibration propagation to the media which may cause annoyance to people who live in the track neighborhood. Train induced vibration also contributes to track settlement, developing track flaws, and increasing life cycle cost of track and supporting structures. The aim of this research is to address this problem by conducting a comprehensive investigation into track dynamics. For this purpose, three-dimensional mass-spring-damper models of vehicle, track and supporting structures were developed and matrices of mass, stiffness, and damping of each subsystem were formed. The response of the whole system was, then, determined by coupling the subsystems using Hertz contact theory. The differential equations of the coupled system were solved by the Newmark integration method and the results including vertical and lateral displacements and forces were presented in the time domain. Since the purpose of this dissertation is to quantify the effect of track and vehicle condition on vibration level, rail defects were also taken into account and rail random irregularities for the vertical profile, Gauge, alignment and cross level (super elevation) were incorporated into a numerical solution. The results of the study show the effect of track and vehicle parameters on the response of the vehicle, track, and substructures. Since Florida and some other states in the United States are very prone to hurricanes, an investigation was conducted into the effect of wind speed on vehicle stability. For this purpose, a curved beam was modeled to consider the influence of track curvature, cant deficiency, wind speed and train speed simultaneously. The results from the study show the maximum allowable values of train speed and axle load for different wind speeds. The findings can be used to decide under what circumstances there is a risk of vehicle overturning and how to avoid it.

A well designed public transportation system can provide convenience to the public, increase the profit of the transportation company, and reduce the cost to the society as a whole. The depot is an important part in the study of transportation systems. The choice of the capacity of the depots is a strategic decision. It will constrain the possible tactical decisions (such as vehicle planning) for a long time, due to the life-span of the infrastructure. It is therefore important to study the impact of the options before they are implemented. The transportation company now is facing the problem that there is no appropriate tool in the decision support system to assess the capacity of the depots and the vehicle planning on the deadhead-kilometer (non-value added trips) and the robustess of the service. The simulation model is an appropriate method for the main part of the study. It can be used to evaluate the key performance indicators of deadhead-kilometer and average delay time, to study the complex interactions among the different elements, and to improve the understanding of the behaviors of the transportation system. The simulation model is useful for evaluating both strategic decisions and tactical decisions. The analyzing tool is designed following the methodology of systems engineering. First the requirements were gathered and translated into specification. The design was then conducted to fulfill the requirements on the conceptual level. Specification of the key classes were then concluded from their functionalities and relationships. The detail design came out with detailed attributions and methods of the classes. The analysis is based on a part of the network which consists of five service lines. According to the analysis, compared to the current design (Scheveningen, Zichtenburg and Lijsterbes), the future alternative with “Remise Zuid” depot and closing down “Lijsterbes” depot achieves 18% reduction on average delay time, but with a cost of 15% of increase in deadhead-kilometer. With the ratings obtained from the policy advisors of HTM, the alternative with “Remise Zuid” outperforms the design of current situation on the overall performance. Though the methodology applies to the entire network, the analysis results so far portaits the impact on these five lines. A more comprehensive study can be conducted with the same method and the input data covering all the operating lines. Some improvement can be made on the management of depots by a better the training of the employees and a clearer definition of job responsibilities.

▼ Insulated Rail Joints (IRJs) are vulnerable to heavy axle loading as evidenced by their frequent replacement in short periods due to various modes of failures they exhibit under the passage of loaded wheels aggravated by the local condition of the track. As the wheel loads and track conditions can be highly variable, IRJs exhibit highly variable service life. The IRJs used in Australia are assembled in factories with high standards of quality control procedure as outlined in manuals and standards; however, their service life varies significantly even under similar traffic condition, which is of a major concern to the rail industry and the society and allied industries that depend on the rail transport. A research hypothesis on the effect of the support system (track) to the short and variable service life of IRJs is, therefore, formulated and examined in this thesis. In spite of the significant role the IRJs play to the control of signalling system and their low and highly variable service life, there is a paucity of literature with regard to the actual mechanical behaviour of the in-service IRJs. This thesis aims at bridging the gap in the knowledge. An extensive field test was conducted on an in-service heavy haul corridor in Australia with the specific aims of understanding the effects of track input to the response of the IRJs. Data on the wheel-rail forces, rail strains, sleeper accelerations and ballast pressure signatures are determined from the experiment. The data are systematically employed to analyse the mechanical behaviour of the IRJs resting on different support conditions relative to a Reference Rail (Ref rail) subjected to the same traffic loading. One of the instrumented IRJs and the Ref rail have been monitored over 16 months to examine the change in their responses under accumulated traffic. A track model containing an IRJ is developed in the GENSYS multi-body dynamic system framework. The developed model is calibrated against the data measured on the Ref rail and then validated using the data from the IRJs. GENSYS is widely used in train dynamic analysis and its usage in detailed track component modelling and examination of performance at component level is first of its kind; the results of which unearth the powerfulness of the platform for track dynamic analysis, albeit the model is complex. The validated GENSYS model is then employed to simulate various scenarios of track support conditions including varied levels of damage beneath the IRJs. The sensitivity of loading and responses of IRJs to the change in IRJ component properties as well as different track support parameters are analysed. Various conditions of deteriorated track including sleeper void (hanging sleepers) and geometry dip are investigated; their effects on the loading and responses of IRJ are discussed. Analysis of results obtained from experiments and numerical simulations have resulted in valuable conclusions on the effects of track input to the response of IRJs, the key of which are as follows: vi 1- The loading and…

Rail wear can result in extensive costs for the track owner if it is not predicted and preventedin an efficient way. To limit these costs, one measure is to predict rail wear through wear simulations. The purpose with this work is to perform simulations of successive rail wear on the Swedish light rail line Tvärbanan in Stockholm, by means of the track-vehicle dynamics software GENSYS in combination with a wear calculation program developed in MATLAB. The simulation procedure is based on a methodology with a simulation set design, where the simulations to be performed are selected through a parametric study. The simulations include track-vehicle simulations, where the wheel-rail contact is modelled according to the Hertzian contact theory together with Kalker’s simplified theory (including the numerical algorithm FASTSIM). The results from the track-vehicle simulations serve as input to the wear calculations. When modelling rail wear Archard’s wear model has been used, including wear coefficients based on laboratory measurements. The measurements have been performed under dry conditions, so the wear coefficients under lubricated conditions (both natural and deliberate lubrication) are reduced by factors estimated by field observations. After the wear depth calculations the wear distribution is smoothed and the rail profile is updated. The simulation procedure continues with a new wear step as long as the desired tonnage is not attained. Four curves of Tvärbanan with different curve radii, ranging from 85 to 410 m, have beenstudied in this work. On three of the curves the high rail is deliberately lubricated, whereas no lubrication has been applied in the widest curve. The vehicle operating the light rail line is an articulated tram with two motor end bogies and one intermediate trailer bogie. The line was opened in August 1999 and extended in one direction one year later. Rail profile measurements have been carried out by SL since March 2002. The traffic tonnage at the selected sites from the opening of the line to the last measurement occasion (September2004) is at most 8.9 mega gross ton per track. The results of the rail wear prediction tool are evaluated by comparing worn-off area of the simulated rail profiles with that of the measured rail profiles. Simulated and measured resultsdo not agree too well, since the simulated rail wear is more extensive than the measured one, especially on the outer rail. However, the shapes of the simulated worn rail profiles are comparable to those of the measured rail profiles.

Les phénomènes dynamiques observés lors de la circulation des trains provoquent des nuisances, notamment sonores et vibratoires, qui sont amplifiées par la présence de défauts sur la roue et sur le rail. Pour les analyser, il est nécessaire de prédire avec robustesse le comportement dynamique des composants impliqués dans l’interaction véhicule-voie et donc de simuler les efforts de contact générés pour des interfaces non idéalisées.L’objectif de cette thèse est donc de proposer un modèle semi-analytique global compatible avec l’intégration de multiples défauts géométriques sur les surfaces en contact. Afin de simuler l’interaction véhicule-voie dans le domaine temporel et garantir une applicabilité en phase de dimensionnement, une attention particulière est portée sur le compromis entre la précision des résultats et les temps de calcul associés.Le modèle ainsi proposé est composé d’un demi-bogie, dont le comportement vertical est représenté par un ensemble de masses-ressorts-amortisseurs, circulant sur une voie ballastée. Cette dernière est assimilée à une poutre bi-appuyée, supportée périodiquement à l’emplacement des traverses. Ces deux systèmes sont couplés en contact grâce à une procédure Distributed Point Reacting Spring (DPRS) sous forme discrétisée.Une validation du modèle est, d’une part, proposée en considérant des travaux antérieurs dans le cas de géométries parfaites. D’autre part, de multiples combinaisons de défauts, localisés comme le méplat ou répartis comme l’usure ondulatoire, sont introduites dans la simulation. La variabilité spatiale, particulière au cas de l’écaillage, est modélisée par des champs aléatoires.

The appearance of dynamic phenomena during the running of train on track leads to issues such as noise and vibration pollution, which can be further amplified by the presence of defects on the treads. In order to analyze them, it is necessary to predict with reliability the dynamic behavior of the vehicle-track interaction components, in particular the contact forces produced by non perfect treads.The aim of this PhD thesis is to provide a semi-analytical vehicle-track interaction model able to take into account multiple defects on the surfaces in contact. In order to conduct simulations in the time-domain and ensure applicability in the sizing phase, a special attention is given on the compromise between the accuracy of the results and the simulation times.The proposed model is therefore composed of half a bogie running on a ballasted track. This latter is modeled by a pinned-pinned beam with periodic supports located at the sleepers while the vertical behavior of the bogie is given by masses, springs and dampers. These two models are coupled in contact by a discretized Distributed Point Reacting Spring (DPRS) procedure.A validation of the model, based on previous work, is firstly proposed for perfect treads. Then, multiple combinations of defects, either localised as wheelflat or spread as corrugation, are introduced in the simulation. The spatial variability, specific to shelling, is…

▼ Train-vehicle collisions at highway-rail grade crossings continue to be a major issue in the US and across the world. Installing additional hardware at individual crossings is expensive, time consuming, and potentially ineffective. To prevent recent trends in safety improvement from plateauing, experts are turning towards novel warning devices that can be applied to all crossings with minimal cost. In-vehicle auditory alerts (IVAAs) could potentially remedy many of the human factor issues related to crossing safety in a cost effective manner. This thesis presents a series of experiments designing and testing an IVAA system for grade level railroad (RR) crossings. Study 1 collected subjective data on a pool of potential in-vehicle auditory alerts from 31 undergraduate participants. The type of IVAAs was varied along a number of dimensions (pitch, repetition, wave shape, wording, voice, etc.). Results from study 1 were used to design a prototype IVAA crossing notification system. A pilot study was conducted to calibrate the simulated driving scenario featuring multiple RR crossings and a compliance behavior coding procedure. Compliance behavior was operationalized as an amount of visual scanning and pedal depression. Study 2 recruited 20 undergraduate participants to drive in a medium fidelity driving simulator featuring four types of RR crossings with and without IVAAs. Results suggest that IVAAs not only inform and remind drivers of how to comply at RR crossings, but also have a lasting effect on driver behavior after the IVAA is no longer presented. Compliance scores were highest among novel RR crossing visual warnings such as crossbucks featuring STOP or YIELD signs. Compliance was lowest for crossbucks alone and active gates in the off position. IVAAs had the largest impact on compliance scores at crossbucks and gates. The discussion includes implications for designing IVAA systems for RR crossings, and the potential implementation of prototype systems as a smartphone application.

Jusqu'à présent les modèles multi-corps d'interaction véhicule-voie ferroviaire utilisent principalement des composants rigides. De tels modèles présentent l’avantage d’un nombre de degrés de liberté limité permettant de réaliser des calculs en temps réel à basses fréquences. En revanche, ils ne permettent pas de prédire avec suffisamment de précision les spectres des efforts de contact roue-rail en raison de l’hypothèse d’éléments rigides qui est assez forte. Aussi ces modèles gagneraient à être améliorés en prenant en considération la flexibilité des éléments. Ceci est possible grâce au couplage éléments finis – dynamique multi-corps. Les travaux réalisés dans le cadre de cette thèse ont pour objectif, l’amélioration des prédictions des efforts d’interaction véhicule-voie par intégration d’essieux et de rails flexibles dans les modèles multi-corps du véhicule et de la voie. Des modèles éléments finis des essieux et de la voie ont été développés et couplés au modèle global de la dynamique multi-corps via des méthodes de réduction de modèles afin de gagner en précisions tout en limitant le nombre de degrés de libertés. Différentes configurations des modèles multi-corps du véhicule et de la voie avec des essieux et des rails flexibles ont été explorées afin d’évaluer les effets de la flexibilité des éléments sur les prédictions des efforts de contact. Les premiers modèles sont réalisés avec des essieux flexibles roulant sur une voie théorique parfaite sans défauts avec des rails rigides en alignement puis en courbe. Ces modèles ont été ensuite modifiés afin d’intégrer la flexibilité des rails ainsi que des excitations générées par les défauts des roues et des rails (usure ondulatoire, méplat de roue et joint de rail).

Multibody models for the study of the vehicle-track interaction used by railway companies consider mainly rigid components. These models are characterized by small number of degrees of freedom allowing real time calculations in low frequency ranges, but these models do not properly estimate real interaction forces because of the strong hypothesis of the components rigidity. These models need to be improved by taking into account the components flexibilities by coupling finite elements analysis with multibody dynamics simulations. The main objective of this study is to develop the multibody models of a railway vehicle and track with flexible wheelsets and flexible rails in order to improve the prediction of vehicle-track interaction forces. Finite element models of wheelset and track are developed and reduced using model reduction methods to reduce their number of degrees of freedom before their integration in the multibody models. Different configurations of vehicle and track models with flexible wheelsets and flexible rails are considered to evaluate the effect of components flexibilities on the contact forces. The first models are made of flexible wheelsets rolling on a perfect track with rigid rails in alignment and curve without irregularities. Then, these models are improved by integration of…

▼ The objective of the research in this dissertation is to use novel adaptive materials called magnetorheological nanocomposites (MRNs) to build semi-active structures, and further apply such smart structures into the vehicle-bridge coupling system of high-speed rail so that the dynamic responses of the bridge can be controlled and suppressed significantly. First, the dynamic behavior of a simplified double-beam system interconnected by an elastic layer is investigated. A semi-analytical method is developed to analyze the natural frequencies and corresponding mode shapes. The dynamic responses of forced system vibration are determined by the modal-expansion method using the natural frequencies and mode shapes obtained from the free vibration analysis. Second, considering the damping effect of the viscoelastic layer, a double-beam system with a viscoelastic layer between two beams is observed. An iteration algorithm with modal-expansion method is used to analyze the dynamic responses of forced system vibration.Third, an active control structure, a semi-active control structure and corresponding control algorithms are developed to suppress the vibration of the double-beam system with elastic layer or viscoelastic layer. In the active control structure, the independent modal space control and linear quadratic regulator are adopted to determine the active control force. With the mode shape filter and dynamic mechanical model, the determinations of stiffness increase and damping increase are obtained.Fourth, a co-simulation method is proposed to complete the dynamic simulation of vehicle-bridge coupling system. The Matlab/Simulink is used to build a platform to ensure MSC/NASTRAN for bridge model and MSC/ADAMS for vehicle model working together. The vehicle-bridge coupling relationships are coded as a program block and inputted into that platform.Finally, the semi-active control structure based on MRNs is inputted into the vehicle-bridge coupling system of high-speed railway to control and suppress the vibration of the bridge. MRNs are applied as the viscoelastic layer between floating slab track and bridge main beam to build the semi-active control structure for bridges. The semi-active control algorithm for MRNs is developed and inputted into that co-simulation platform. Numerical experiments have been made to illustrate and verify the efficiency of the proposed semi-active control structure in the end.

▼

A conceptual design of an innovative two-axle lightweight railway vehicle for commuter services is carried out at KTH Railway Group. An active wheelset steering is introduced to improve the curving performance of the vehicle, which is one of the critical performance requirements. This thesis aims to improve the steering performance of the active wheelset steering. Look-up tables for estimating time-varying wheel-rail contact parameters are introduced to supervise a simple PID controller of the active steering system in order to improve steering performance. The look-up table (LUT) estimation is focused on time-varying wheel-rail contact parameters, including creep coefficients and contact patch variables due to their direct influence on curving performance and lateral stability of the wheelset. As a result, the estimated longitudinal unit creep forces (UCF) have the potential to supervise the gains determination of PID controller because it can appropriately distinguish running conditions. The estimation of longitudinal UCF is achieved by the combination of the results from the LUT of creep coefficients and the LUT of contact patch variables. The result from longitudinal unit creep force estimation is shifted to the first quadrant to use as critical gain in the Ziegler-Nichols tuning method for the PID controller. The critical oscillation period for PID tuning can be expressed as a function of vehicle speed. Consequently, the PID controller for the active steering system uses time-varying gains with real-time tuning. The proposed control system for active wheelset steering is validated with nine running conditions using SIMPACK and MATLAB/Simulink co-simulation. The proposed control system provides a stable wheelset lateral displacement control regardless of the running condition. The active steering system significantly reduces wheel-rail wear, which demonstrates the effectiveness of the proposed active steering system.

KTH:s Järnvägsgruppen utvecklar en konceptuell design av ett innovativt, två-axligt, lättvikts järnvägsfordon för tunnelbana eller pendeltåg. En aktiv hjuparsstyrning introduceras för att förbättra kurvtagningsförmågan hos fordonet, vilket är ett av de kritiska prestandakraven hos dessa fordon. Det här examensarbetet har som målsättning att förbättra styrningsprestandan av den aktiva hjulsatsstyrningen. För att uppskatta tidsvarierande hjul-rälskontaktparametrar introduceras pre-definierade tabeller (LUT) som en övervakning av en enkel PID-kontroll för det aktiva styrningssystemet, för att förbättra styrprestandan. Uppskattningen som baseras på tabellen fokuserar på tidsberoende hjul-rälsparametrar, inklusive krypkoefficienter och kontaktytans storlek och form. Dessa variabler är i fokus på grund av deras direkta effekt på kurvtagningsförmågan och den laterala stabiliteten hos hjulparet. Den uppskattade longitudinala enhets krypkraften (UCF) har potential att bestämma förstärkningen hos PID-kontrollen på grund av att den, på ett lämpligt sätt, kan skilja mellan olika körtillstånd.…

▼ During the last decade, a novel methodology for wheel wear simulation has been developed in Sweden. The practical objective of this simulation procedure is to provide an integratedengineering tool to support rail vehicle design with respect to wheel wear performance and detailed understanding of wheel-rail interaction. The tool is integrated in a vehicle dynamicssimulation environment.The wear calculation is based on a set of dynamic simulations, representing the vehicle, the network, and the operating conditions. The wheel profile evolution is simulated in an iterativeprocess by adding the contribution from each simulation case and updating the profile geometry.The method is being validated against measurements by selected pilot applications. To strengthen the confidence in simulation results the scope of application should be as wide aspossible in terms of vehicle classes. The purpose of this thesis work has been to try to extend the scope of validation of this method into the light rail area, simulating the light rail vehicleA32 operating in Stockholm commuter service on the line Tvärbanan.An exhaustive study of the wear theory and previous work on wear prediction has been necessary to understand the wear prediction method proposed by KTH. The dynamicbehaviour of rail vehicles has also been deeply studied in order to understand the factors affecting wear in the wheel-rail contact.The vehicle model has been validated against previous studies of this vehicle. Furthermore new elements have been included in the model in order to better simulate the real conditionsof the vehicle.Numerous tests have been carried out in order to calibrate the wear tool and find the settings which better match the real conditions of the vehicle.Wheel and rail wear as well as profile evolution measurements were available before this work and they are compared with those results obtained from the simulations carried out.The simulated wear at the tread and flange parts of the wheel match quite well the measurements. However, the results are not so good for the middle part, since themeasurements show quite evenly distributed wear along the profile while the results from simulations show higher difference between extremes and middle part. More tests would benecessary to obtain an optimal solution.

▼ Railroad transportation is one of the most cost-effective and energy-efficient modes of land transportation. With an eye toward improving these efficiencies, many efforts have focused on developing high speed railways. Traditionally railways have utilized passive suspension systems, but maintaining dynamic stability at higher speeds demands enhancements to existing rail vehicle suspensions. One strategy to improve dynamic performance is to incorporate active or semi-active elements, such as force actuators or variable dampers, within the suspension system. Modern day road and rail vehicles often utilize such actively-controlled suspensions to improve stability, ride comfort and ride quality at high speeds. The dynamic performance of such mechatronically-controlled suspension systems is related closely to the congruence of the design of passive elements in conjunction with the chosen control system strategy. Historically, design of controlled dynamic systems has followed a sequential process (mechanical design followed by control design). In the field of mechatronics, engineers typically use design rules or heuristics that help account for design coupling, but cannot produce system optimal designs. Passive elements are optimally designed first, followed by the addition of controllers for system performance improvements. New integrated design strategies are required to realize the full potential of such advanced complex dynamic systems and to capitalize on design coupling. This thesis aims to explore and apply a recently developed synergistic approach to design of controlled dynamic systems, called co-design. Theoretical models of existing partitioned, optimization-based design methods are compared to this combined active and passive system design strategy. Parameters for a reduced and a full-scale rail vehicle model are then designed using the developed optimal design formulations. Different control techniques within the co-design framework are tested and compared. Typically feedback controllers are required for actual implementation of control strategies. Early-stage co-design strategies are normally based on open-loop control, therefore, are limited for functional implementation. However, co-design methods provide designers with better knowledge about the true performance limits of dynamic systems, help them make more informed design decisions, and provide a foundation for development of implementable feedback control systems. The results obtained in this thesis show significant improvements achieved by co-design strategies over passive system design and sequential design approaches. The results also demonstrate the potential of this framework in helping systematic selection of optimal plant design variables, controller architecture, and implementable control techniques. Future work includes designing practical feedback controllers built upon results from co-design strategies for rail vehicles using non-linear vehicle models to provide a complete active rail suspension solution.
