摘要：

In this paper, a computational study using the moving element method is carried out to investigate the dynamic response of a high-speed rail (HSR) experiencing sudden braking. The train is modeled as a 10-DOF system of interconnected spring-damping units. The Hertz contact theory is employed to account for the nonlinear contact force between the wheel and rail. The railway track is treated as an Euler-Bernoulli beam resting on a two-parameter elastic damped foundation. The effects of wheel sliding, initial train deceleration, initial train speed and the severity of railhead roughness on the dynamic response of the HSR are investigated.
