Abstract
A simulation method which can solve the dynamic interaction problem between high speed railway vehicles and railway structures was develped using a three dimentional mass-spring-damper linked vehicle model and a finite element structure model. In this method, a simplified model of the creep phenomenon between wheel and rail is adopted, and the lateral elasticity of rail is also taken into account to simulate rolling action of wheelsets. A modal superposition method is adopted to solve this problem efficiently. The formulation and numerical techniques are described in this paper.
