Abstract

The running behaviour of a passenger coach on a track with irregularities is simulated using an enhanced multibody model, which takes the structural flexibilities of both wheelsets and rails into account and which uses a highly detailed wheel-rail contact model. The results show that the strength of the impact of the structural flexibilities depends on the wheel-rail contact geometry. This combined impact affects the running behaviour as well as the stress distribution within the wheel-rail contact.
