In this work, available software from CHARMEC projects for the analysis of dynamic train–track interaction, of wear and rolling contact fatigue of wheel and rail, and of ground vibrations and railway noise, is being extended and integrated. Calculated high-frequency wheel–rail contact forces have been validated against forces measured by Interfleet Technology during a field tests carried out in October 2002 with an x2 passenger train on rough (corrugated) rails. The application of CHARMEC's computer program DIFF has been broadened to improve the handling of frequencies below 50 Hz.
The overall aim of the project is to develop user-friendly computer tools for the rational design of both the whole track
and its individual components.
