Overview on the DLR RailwayDynamics Library.

The newly released commercial DLR RailwayDynamics Library is intended to support the design, optimization and control development as well as hardware- and software-inthe-loop testing of railway vehicles mainly on the system level. To this aim, it provides the capability to consider vehicle dynamics issues such as traction, comfort and safety in multi-domain engineering tasks by preparation of vehicle, track, wheel-rail contact models and roller rig scenarios on different levels of detail. Exploiting several precursor papers on specific railway modeling topics, their models have been collected and reorganized in order to propose a sound modeling framework dedicated to railway dynamics. The paper gives an overview on particular concepts and ideas of the library, presents several application examples and discusses two approaches to organize multi-domain modeling.
