Wheel-rail dynamic interaction

A better understanding of wheel-rail dynamic interaction is necessary for the capacity increase of railway transportation. This chapter briefly introduces the consequences, modeling and detection methods of wheel-rail dynamic interaction, and maintenance of the weak track spots where wheel-rail dynamic interaction often occurs. Wheel-rail...

A numerical study on waves induced by wheel-rail contact

Recent finite element (FE) simulations have revealed the generation and propagation of waves in rail surfaces induced by wheel-rail frictional rolling. These waves have rarely been addressed in the literature. This paper presents an in-depth analysis of these waves, aiming to give new insights into the contact mechanics, a research area in...

Numerical study of wheel-rail impact contact solutions at an insulated rail joint

This paper presents an analysis of the transient contact solutions of wheel-rail frictional rolling impacts calculated by an explicit finite element model of the wheel-insulated rail joint (IRJ) dynamic interaction. The ability of the model to simulate the dynamic behavior of an IRJ has been validated against a comprehensive field measurement in...
