报告摘要：

This talk will give an introduction to the mechanics problems in the train-track interactionsystems as well as the resulting degradation and damages. They are generally pertinent to wheel-rail systems including high-speed, heavy haul, conventional railways and metro. At the core is the frictional rolling contact and the associated adhesion, stick-slip, wear, deformation and fatigue. Excited by the rolling wheels, dynamic loading arises in the system and the components and at the interfaces. This loading increases with the speed of the trains and the stiffness of the track structure. As a result dynamics are becoming more important in high speed railways for design, maintenance and condition monitoring of the system, components and the interfaces of wheel-rail, fastening and slabs.This concerns structure, continuum and material mechanics and design. The focus of the talk is on the aspects of high frequency dynamics.
