In order to avoid structural deterioration and effects on running safety caused by pressure wave and aerodynamic impact when trains pass by each other at high-speed, from the coupling relationship between train and air, the flow field equations and dynamics equations of multi-body systems were solved at the same time by integrating the Finite Volume Method of Computational Fluid Dynamics and numerical simulation method of Multi-Body Systems Dynamics. Then, the pressure wave, response of carbody and the running safety were analyzed. The results show that, the pressure on the train waves, aerodynamic load impacts, and the running safety decreases. The main factors are derailment coefficient and lateral wheelset force, and the changes of Wheel load reduction rate and Vertical wheel rail force are inconspicuous.
