The effect of track irregularity and wheel load on the dynamic response of a high-speed rail system

In this paper, a computational study using the moving element method (MEM) was carried out to investigate the dynamic response of a high-speed rail (HSR). A new formulation for calculating the structural matrices of the moving element is proposed. Two wheel-rail contact problems will be examined. On...
