Methods for the virtual design of Mechatronic Railway Vehicles

Abstract

The prime condition for the virtual design of mechatronic railway vehicles is a software environment comprising the different computational engineering tools being interconnected by efficient interfaces. The paper presents such an environment with a multibody system software in its centre and a couple of interfaces to other engineering software tools around. Especially in view of mechatronics, the different types of coupling to control engineering software are of interest. The simulation of railway vehicles calls for a specific module describing, besides others, the highly nonlinear contact between wheel and rail. The state-of-the-art of such a simulation tool chain is illustrated for the complex analysis and design issue of a “Mechatronic Train”.
