Coupled and Constrained Problems in Vehicle System Dynamics
Abstract: New developments in automotive and railway engineering such as active safety systems (ABS, ESP, ...), high-speed trains or lightweight constructions are strongly based on computer simulations and scientific computing in the field of vehicle system dynamics. The modelling of mechanical, hydraulic and electronic system components results in coupled systems of non-linear time-dependent differential equations that have to be solved numerically in the typical hardware and software environment of industrial development departments. In the talk we will discuss model reduction and time integration methods that are tailored to industrial simulation packages from multibody dynamics. The methods are extended by a numerical sensitivity analysis to study the long-term running behaviour of wheel-rail systems for varying vehicle speed. Finally a new class of stabilized modular time integration methods is shown that has been used successfully for models of complex coupled technical systems requiring the coupling of two or more simulation packages from different fields of application.| Zeit: | Freitag, 30.
