Book excerpt: Dynamics of Coupled Systems in High-Speed Railways: Theory and Practice presents the relationship between various coupled systems that can affect train operation, including interaction between track and train, the pantograph-catenary system and train, power supply system and train, and airflow and train, with respect to the structure and characteristics of high-speed railway. The overall simulation optimization and control are achieved based on an analysis of the dynamics generated by coupled systems in high-speed trains, with a theoretical framework for the dynamics presented in the book. Presents the first book available on the dynamics of coupled systems in high-speed trains Provides a systematic view of high-speed vehicle dynamics, covering the issues that are especially concerned for high speed operations, such as high-speed pantograph and catenary, aerodynamic characteristics and running stability of high-speed trains Covers the optimization of dynamic performance, the design of parameters, the simulation of high-speed train service processes, and the identification of high-speed train state and condition assessment

Book Synopsis Dynamics of Railway Vehicle Systems by : Vijay Garg

Download or read book Dynamics of Railway Vehicle Systems written by Vijay Garg. This book was released on 2012-12-02. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of Railway Vehicle Systems offers a comprehensive and analytical treatment of the rail-wheel interaction problem and its effect on vehicle dynamics. The development of mathematical models and their applications to dynamic analyses and the design of railway vehicles are discussed. This book consists of 11 chapters and opens with an overview of the background material required to study the dynamics of railway vehicles, with emphasis on analytical techniques used to determine the dynamic response of single- and multiple-degree-of-freedom systems. Numerical solutions of linear and nonlinear dynamic systems are also given, and various problems associated with the dynamic behavior of railway vehicles are addressed. Several mathematical models are proposed to study these problems. The following chapters focus on the wheel-rail rolling contact theories being applied in railway vehicle dynamics problems; modeling of the vehicle and its components on both tangent and curved railroad tracks; and the interaction between railway vehicles and bridges. The final chapter underscores the needs for validating mathematical models that are used to study the dynamic behavior of railway vehicles and train consists. This monograph will be of value to design and research engineers, transportation officials, mathematicians, analysts, and research workers interested in the dynamics of railway vehicle systems.

Book Synopsis Vehicle–Track Coupled Dynamics by : Wanming Zhai

Download or read book Vehicle–Track Coupled Dynamics written by Wanming Zhai. This book was released on 2019-09-19. Available in PDF, EPUB and Kindle. Book excerpt: This book systematically presents the theory, numerical implementation, field experiments and practical engineering applications of the ‘Vehicle–Track Coupled Dynamics’. Representing a radical departure from classic vehicle system dynamics and track dynamics, the vehicle–track coupled dynamics theory considers the vehicle and track as one interactive and integrated system coupled through wheel–rail interaction. This new theory enables a more comprehensive and accurate solution to the train–track dynamic interaction problem which is a fundamental and important research topic in railway transportation system, especially for the rapidly developed high-speed and heavy-haul railways. It has been widely applied in practical railway engineering. Dr. Wanming Zhai is a Chair Professor of Railway Engineering at Southwest Jiaotong University, where he is also chairman of the Academic Committee and Director of the Train and Track Research Institute. He is a member of the Chinese Academy of Sciences and one of the leading scientists in railway system dynamics. Professor Zhai is Editor-in-Chief of both the International Journal of Rail Transportation, published by Taylor & Francis Group, and the Journal of Modern Transportation, published by Springer. In addition, he is a trustee of the International Association for Vehicle System Dynamics, Vice President of the Chinese Society of Theoretical and Applied Mechanics, and Vice President of the Chinese Society for Vibration Engineering. /div

Book Synopsis System Dynamics and Long-Term Behaviour of Railway Vehicles, Track and Subgrade by : Karl Popp

Download or read book System Dynamics and Long-Term Behaviour of Railway Vehicles, Track and Subgrade written by Karl Popp. This book was released on 2013-06-06. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades completely new technologies for high speed railway vehicles have been developed. The primary goals have been to increase traction, axle load, and travelling speed, and to guarantee the safety of the passengers. However, new developments have revealed new limitations: settlement and destruction of the ballast and the subgrade lead to deterioration of the track; irregular wear of the wheels causes an increase in overall load and deterioration in passenger comfort; and damage of the running surfaces of the rail and the wheel is becoming more frequent. These problems have been investigated in the Priority Programme SPP 1015 supported by the Deutsche Forschungsgemeinschaft (DFG), with the goal of better understanding of the dynamic interaction of vehicle and track, and the long-term behavior of the components of the system. The book contains the scientific results of the programme as presented at the concluding colloquium held at University of Stuttgart, Germany, 2002.
