| Abstract: | The purpose of this study is to propose a coupled train model with a multibody system considering three-dimensional wheel/rail contact geometry and to assess the safety of high-speed railway vehicles. Railway vehicles are becoming lighter and are running at increased speeds, so it is necessary to discuss their safety when subjected to a crosswind. In this paper, we use the proposed model in a situation presupposing strong crosswinds in order to analyze the behavior of coupled trains under this condition. We discuss the modeling and formulation of a coupled train as well as wheel unloading ratios. Our results show that vibration of a car body is largest in the wheel unloading ratios of the car body when the frequency of the car body is close to the second-mode natural frequency of the vehicle system.
