This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Competition among automotive manufacturers has increased a lot in the recent years. One of the main concerns regarding the suspension design of a vehicle is its ride comfort and handling performance characteristics. This thesis aims to create new methodologies for comfort and handling evaluation as well as to make a brief study regarding the influence that the characteristics of a damper have over the vehicle behaviour. The thesis is divided into two parts. In its first part, this thesis proposes new virtual road scenarios, some of which allow evaluating simultaneously ride comfort and handling performance during a vehicle dynamics simulation. These roads are created as a standard CRG format which can be used by different software in the field of vehicle dynamics. In its second part, a total of five different scenarios are chosen in order to study the differences that two different software and two different tyre models have over the results. Three models are used: Adams Car with FTire, Adams Car with MF-Tyre and CarMaker with MF-Tyre. Also, some metrics are defined for each scenario in order to compare quantitatively the results between these three models. Results have shown important differences regarding the tyre model in the impact scenarios and minor differences regarding the software in all scenarios except for the primary ride, which provides good accuracy using the simplest model: CarMaker with MF-Tyre. This configuration also presents much shorter running simulation time. Basically, the best configuration to carry out the simulation would be Adams Car with FTire model for all scenarios except for the primary ride, in which CarMaker with MF-Tyre model could be used too. Also within the second part, a sensitivity analysis is done. The original spline of the front damper is converted into a bilinear spline defined by six different parameters, which are modified at two different levels: 40% lower and higher than baseline. Then, the five scenarios previously defined are used to study how a certain parameter of the damper spline affects each metric. Apart from confirming the expected results (a low level of damping is needed to improve comfort while a high level of damping is needed to improve handling or road holding), this methodology quantifies and helps finding the optimum compromise between ride comfort and handling performance of a damper.

Available in PDF, EPUB and Kindle. Book excerpt: Simulation is the art of using tools – physical or conceptual models, or computer hardware and software, to attempt to create the illusion of reality. The discipline has in recent years expanded to include the modelling of systems that rely on human factors and therefore possess a large proportion of uncertainty, such as social, economic or commercial systems. These new applications make the discipline of modelling and simulation a field of dynamic growth and new research. Stanislaw Raczynski outlines the considerable and promising research that is being conducted to counter the problems of uncertainty surrounding the methods used to approach these new applications. It aims to stimulate the reader into seeking out new tools for modelling and simulation. Examines the state-of-the-art in recent research into methods of approaching new applications in the field of modelling and simulation Provides an introduction to new modelling tools such as differential inclusions, metric structures in the space of models, semi-discrete events, and use of simulation in parallel optimization techniques Discusses recently developed practical applications: for example the PASION simulation system, stock market simulation, a new fluid dynamics tool, manufacturing simulation and the simulation of social structures Illustrated throughout with a series of case studies Modelling and Simulation: The Computer Science of Illusion will appeal to academics, postgraduate students, researchers and practitioners in the modelling and simulation of industrial computer systems. It will also be of interest to those using simulation as an auxiliary tool.

Download or read book Optimization and Optimal Control in Automotive Systems written by Harald Waschl and published by Springer. This book was released on 2014-03-20 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book demonstrates the use of the optimization techniques that are becoming essential to meet the increasing stringency and variety of requirements for automotive systems. It shows the reader how to move away from earlier approaches, based on some degree of heuristics, to the use of more and more common systematic methods. Even systematic methods can be developed and applied in a large number of forms so the text collects contributions from across the theory, methods and real-world automotive applications of optimization. Greater fuel economy, significant reductions in permissible emissions, new drivability requirements and the generally increasing complexity of automotive systems are among the criteria that the contributing authors set themselves to meet. In many cases multiple and often conflicting requirements give rise to multi-objective constrained optimization problems which are also considered. Some of these problems fall into the domain of the traditional multi-disciplinary optimization applied to system, sub-system or component design parameters and is performed based on system models; others require applications of optimization directly to experimental systems to determine either optimal calibration or the optimal control trajectory/control law. Optimization and Optimal Control in Automotive Systems reflects the state-of-the-art in and promotes a comprehensive approach to optimization in automotive systems by addressing its different facets, by discussing basic methods and showing practical approaches and specific applications of optimization to design and control problems for automotive systems. The book will be of interest both to academic researchers, either studying optimization or who have links with the automotive industry and to industrially-based engineers and automotive designers.
Download or read book The Multibody Systems Approach to Vehicle Dynamics written by Michael Blundell and published by Elsevier. This book was released on 2004-08-21 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multibody Systems Approach to Vehicle Dynamics aims to bridge a gap between the subject of classical vehicle dynamics and the general-purpose computer-based discipline known as multibody systems analysis (MBS). The book begins by describing the emergence of MBS and providing an overview of its role in vehicle design and development. This is followed by separate chapters on the modeling, analysis, and post-processing capabilities of a typical simulation software; the modeling and analysis of the suspension system; tire force and moment generating characteristics and subsequent modeling of these in an MBS simulation; and the modeling and assembly of the rest of the vehicle, including the anti-roll bars and steering systems. The final two chapters deal with the simulation output and interpretation of results, and a review of the use of active systems to modify the dynamics in modern passenger cars. This book intended for a wide audience including not only undergraduate, postgraduate and research students working in this area, but also practicing engineers in industry who require a reference text dealing with the major relevant areas within the discipline. - Full of practical examples and applications - Uses industry standard ADAMS software based applications - Guides readers from modelling suspension movement through to full vehicle models able to perform handling manoeuvres

Download or read book Advanced Autonomous Vehicle Design for Severe Environments written by V.V. Vantsevich and published by IOS Press. This book was released on 2015-10-20 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical vehicle dynamics, which is the basis for manned ground vehicle design, has exhausted its potential for providing novel design concepts to a large degree. At the same time, unmanned ground vehicle (UGV) dynamics is still in its infancy and is currently being developed using general analytical dynamics principles with very little input from actual vehicle dynamics theory. This technical book presents outcomes from the NATO Advanced Study Institute (ASI) ‘Advanced Autonomous Vehicle Design for Severe Environments’, held in Coventry, UK, in July 2014. The ASI provided a platform for world class professionals to meet and discuss leading-edge research, engineering accomplishments and future trends in manned and unmanned ground vehicle dynamics, terrain mobility and energy efficiency. The outcomes of this collective effort serve as an analytical foundation for autonomous vehicle design. Topics covered include: historical aspects, pivotal accomplishments and the analysis of future trends in on- and off-road manned and unmanned vehicle dynamics; terramechanics, soil dynamic characteristics, uncertainties and stochastic characteristics of vehicle-environment interaction for agile vehicle dynamics modeling; new methods and techniques in on-line control and learning for vehicle autonomy; fundamentals of agility and severe environments; mechatronics and cyber-physics issues of agile vehicle dynamics to design for control, energy harvesting and cyber security; and case studies of agile and inverse vehicle dynamics and vehicle systems design, including optimisation of suspension and driveline systems. The book targets graduate students, who desire to advance further in leading-edge vehicle dynamics topics in manned and unmanned ground vehicles, PhD students continuing their research work and building advanced curricula in academia and industry, and researchers in government agencies and private companies.

Download or read book Vehicle Dynamics and Control written by Rajesh Rajamani and published by Springer Science & Business Media. This book was released on 2011-12-21 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vehicle Dynamics and Control provides a comprehensive coverage of vehicle control systems and the dynamic models used in the development of these control systems. The control system applications covered in the book include cruise control, adaptive cruise control, ABS, automated lane keeping, automated highway systems, yaw stability control, engine control, passive, active and semi-active suspensions, tire-road friction coefficient estimation, rollover prevention, and hybrid electric vehicles. In developing the dynamic model for each application, an effort is made to both keep the model simple enough for control system design but at the same time rich enough to capture the essential features of the dynamics. A special effort has been made to explain the several different tire models commonly used in literature and to interpret them physically. In the second edition of the book, chapters on roll dynamics, rollover prevention and hybrid electric vehicles have been added, and the chapter on electronic stability control has been enhanced. The use of feedback control systems on automobiles is growing rapidly. This book is intended to serve as a useful resource to researchers who work on the development of such control systems, both in the automotive industry and at universities. The book can also serve as a textbook for a graduate level course on Vehicle Dynamics and Control.

Download or read book Dynamics of Vehicle Road Coupled System written by Shaopu Yang and published by Springer. This book was released on 2015-04-29 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vehicle dynamics and road dynamics are usually considered to be two largely independent subjects. In vehicle dynamics, road surface roughness is generally regarded as random excitation of the vehicle, while in road dynamics, the vehicle is generally regarded as a moving load acting on the pavement. This book suggests a new research concept to integrate the vehicle and the road system with the help of a tire model, and establishes a cross-subject research framework dubbed vehicle-pavement coupled system dynamics. In this context, the dynamics of the vehicle, road and the vehicle-road coupled system are investigated by means of theoretical analysis, numerical simulations and field tests. This book will be a valuable resource for university professors, graduate students and engineers majoring in automotive design, mechanical engineering, highway engineering and other related areas.
