Simulations of a high-speed train running on a floating ladder track with rail irregularity

Abstract

In this paper, the finite element formulation and efficient numerical method to solve the combined dynamic behavior of a high-speed train and a newly developed floating ladder track are given. A mechanical model to describe the interaction between wheel and rail is given. Various simulations of a high-speed vehicle running at 350km/h on the ladder track with local rail irregularities defined are conducted to study the impact behavior between the vehicle and the track.
