Abstract:
The wheel-rail interface is one of the most complex contact pairs from a tribological perspective, as it is an open system where contact conditions vary constantly. Among the influencing factors, wear plays a fundamental role in the alteration of the wheel/rail contact geometry and consequently the contact behavior and eventually the performance of the vehicles since the wheel/rail contact mechanics and wear are closely connected with the phenomenon of creep and adhesion. This talk provides a framework for the correlation between contact mechanics and wear with discussions of the challenges and solutions of wheel/rail contact modelling and wear prediction.
