Abstract: Virtual prototyping represents an important way for cost and time efficient design of future railway vehicles. SIMPACK, as a universally applicable simulation software for mechanical and mechatronic systems based on a multibody systems approach and providing the system engineer with powerful bi-directional interfaces to established computer-aided engineering software, serves as a reliable and efficient tool for this process. A comprehensive general wheel-rail module extends the software to the entire range of railway vehicles. Besides a short general description including the use of its interfaces, the emphasis is laid upon the contact modelling between wheel and rail for which a recently developed quasi-elastic contact model is applied. Two complex industrial simulation tasks from the field of advanced railway technology demonstrate the concurrent co-operation of all these features.

Keywords: simulation; railway vehicle dynamics; virtual prototyping; multibody systems; mechatronic systems; wheel-rail contact; creepage control; tilting technique.
