Abstract [en]

The conditions in wheel rail contacts can be both mild and severe. Predicting the friction and the wear in such contacts is generally thought to be rather difficult and uncertain. This paper, however, addresses these tasks and will outline some possibilities for predicting friction and wear in rolling and sliding contacts as in wheel-rail contacts. In a rolling and sliding contact, the two interacting surfaces characteristically move at different speeds in a tangential direction. The Tribology Group at KTH Machine Design has worked on simulating friction and wear in rolling and sliding contacts for more than 20 years. The modelling principles the group has successfully used are based on (i) the single-point observation method and (ii) treating friction and wear as initial-value processes. Simple examples will be presented, demonstrating how these principles can be used.
