Ground vehicle systems are composed of the vehicles themselves interacting dynamically with their guideways. Automobiles on uneven roads, and railways on flexible tracks are prominent representatives of ground vehicle systems. The motion of a vehicle is subject to propulsion, guidance and suspension forces interacting within the system and affecting passengers and goods carried on the vehicle. The dynamical analysis of this interplay of forces and motions is the subject of vehicle dynamics
This course presents an integrated approach of the common fundamentals of rail and road vehicles based on multibody system dynamics, rolling wheel contact and control system design. The mathematical methods presented allow an efficient and reliable analysis of the resulting state equations, and may also be used to review simulation results from commercial vehicle dynamics software.
The course will also provide a better understanding of the basic physical phenomena of vehicle dynamics most important for the engineering practice in research and in industry. Particular attention will be paid to developments of future road and rail vehicles. Again, mechatronic trains and mechatronic cars show many similarities which result in an interdisciplinary stimulation of the design concepts used.
The automation of individual vehicle traffic on roads, and on rail, is an important point of issue in the future: drivers reading the newspaper, watching television, surfing the internet while their vehicles automatically find their way to the desired destination – rapid and secure. The course will cover two recent developments. The Railcab is an individual vehicle on existing railway tracks offering point-to-point traffic in a complex controlled network. The Driver Assistance Systems are devices to control distance and keep in lane on existing roads, relieving the driver and leading to a significant improvement in driving safety and comfort.
The theoretical foundations will be delivered by lecturers from academia while the advanced applications are presented by experts from industry. Thus, the course offers a unique opportunity for the participants to understand the fundamental principles of vehicle dynamics that are the basis for future developments, and to learn about automated individual vehicles on roads and on tracks which are currently under development.
