Abstract：In order to treat the time-consuming problem of synchronous simulation of aero-dynamics and dynamics of train system, a new simulation method is proposed based on the Arbitrary Lagrangian Eulerian(ALE). First, the models for side-wind computational fluid dynamics and train multibody system dynamics are built up respectively. Then, the combined simulation is performed through parameters passing, solution control and dynamic grid, where the track excitations are not considered, the final equilibrium state of train in side-wind is acquired state by state, and the steady attitude and the corresponding aerodynamic loads caused by the side-wind are computed more efficiently. Finally, the aerodynamic loads and track excitations are applied on the train multibody system, the dynamical performance and safety index is analyzed.
