A non-linear three-dimensional model for track/vehicle systems

Rail traffic is generally regarded as environmentally friendly. Yet there still remains an enormous international need to implement economic and environmentally-friendly track and vehicle system technology. A suitable track/vehicle interaction solution may be found in M3RAIL, a non-linear, 3D model, developed at the Department of Railway Systems at the University of Karlsruhe. The M3RAIL model is intended to reproduce vehicle energy effects on tracks. The first step towards this is optimising wheel/rail interaction to reduce and prevent low frequency vibrations. This includes not only vehicle innovations but also suggestions for track development. M3RAIL especially aims to improve short time dynamic modelling with respect to effects on rider comfort and long-term construction life span. By capturing the dynamic in three dimensions, the needed track/vehicle components are presented. For the covering abstract see ITRD E125214.
