Book Description
Why is knowledge of soil stress and deformation state important for off-road locomotion? How do you measure soil stress and deformation under wheel loads? What are the actual values of stresses and deformation in soil or snow under a passing wheel? Providing answers to these questions and more, Dynamics of Wheel–Soil Systems: A Soil Stress and Deformation-Based Approach is a practical reference for anyone who works with experiment design and data analysis of soil stress and deformation measurements under vehicle load. Based on the author’s 15 years of experience in field experimentation on wheel–soil dynamics, the book describes methods and devices for soil stress and deformation measurements and presents numerical data from full-scale field experiments. These methods offer practical solutions to methodological problems that may arise during the design and preparation of field experiments. Provides technical information on measuring, modeling, and optimizing off-road vehicle traction—including a novel method for describing off-road traction Provides rare experimental data on soil stress and deformation under a variety of wheeled and tracked vehicles Supplies solutions for designing, building, and using soil or snow pressure transducers and sensors Compiles original experimental data on soil degradation due to agricultural machinery traffic and soil compaction Explains how to create dynamic models of wheel–soil systems based on experimental data A valuable reference on an important area of terramechanics, this book shows how to analyze and model wheel–soil interactions to create more effective designs for a range of vehicle types.

Book Description
Dynamics of Rail Transit Tunnel Systems develops the dynamic theory of a rail transit tunnel system and provides research methods for the evaluation of long-term settlement of rail transit tunnels in soft soil, the service performance of tunnel structures, and the characterization of environmental vibration induced by trains. In recent years, a large number of rail transit tunnels have been constructed and put into operation, particularly in China. To evaluate the time-dependent degradation of tunnel structures and train-induced environmental vibration, a reliable model must be established to determine the dynamic response of a vehicle-track-tunnel-soil system, hence the introduction of this timely resource. Provides full theoretical background to help the reader gain an in-depth understanding of the various methods used for dynamic analysis of a rail transit tunnel system Develops the dynamics theory and method of a rail transit tunnel system under the context of challenging engineering problems Presents methods for analyzing the dynamic responses of rail transit tunnel-soil systems Looks at problems that need to be solved in the future and proposes potential directions for future research

Book Description
This unique and up-to-date work surveys the use of mechatronics in rail vehicles, notably traction, braking, communications, data sharing, and control. The results include improved safety, comfort, and fuel efficiency. Mechatronic systems are a key element in modern rail vehicle design and operation. Starting with an overview of mechatronic theory, the book goes on to cover topics including modeling of mechanical and electrical systems for rail vehicles, open and closed loop control systems, sensors, actuators and microprocessors. Modern simulation techniques and examples are included throughout, and numerical experiments and developed models for railway application are presented and explained. Case studies are used, alongside practical examples, to ensure that the reader can apply mechatronic theory to real world conditions. These case studies include modeling of a hybrid locomotive and simplified models of railway vehicle lateral dynamics for suspension control studies. Rail Vehicle Mechatronics provides current and in-depth content for design engineers, operations managers, systems engineers and technical consultants world-wide, working with freight, passenger, and urban transit railway systems.

Book Description
Automotive Accident Reconstruction: Practices and Principles introduces techniques for gathering information and interpreting evidence, and presents computer-based tools for analyzing crashes. This book provides theory, information and data sources, techniques of investigation, an interpretation of physical evidence, and practical tips for beginners. It also works as an ongoing reference for experienced reconstructionists. The book emphasizes three things: the theoretical foundation, the presentation of data sources, and the computer programs and spread sheets used to apply both theory and collected data in the reconstruction of actual crashes. It discusses the specific requirements of reconstructing rollover crashes, offers background in structural mechanics, and describes how structural mechanics and impact mechanics are applied to automobiles that crash. The text explores the treatment of crush energy when vehicles collide with each other and with fixed objects. It delves into various classes of crashes, and simulation models. The framework of the book starts backward in time, beginning with the analysis of post-crash vehicle motions that occurred without driver control. Applies time-reverse methods, in a detailed and rigorous way, to vehicle run-out trajectories, utilizing the available physical evidence Walks the reader through a collection of digital crash test data from public sources, with detailed instructions on how to process and filter the information Shows the reader how to build spread sheets detailing calculations involving crush energy and vehicle post-crash trajectory characteristics Contains a comprehensive treatment of crush energy This text can also serve as a resource for industry professionals, particularly with regard to the underlying physics.
