Abstract
By taking real domestic CRH high-speed trains as research object, using the Computational Fluid Dynamics software Starccm+ to carry out numerical simulation calculations when the train runs in different vehicle speeds and cross-wind speeds, We get aerodynamic loads in diverse working conditions. Furthermore, these loads are introduced into the Dynamics Simulation Software SIMPACK, which calculates some running stability parameters such as the derailment coefficient and the reduction rate of wheel load in different cross-wind and vehicle speeds. The calculation indicates that the higher the wind speed is, the lower the vehicle's maximum operating speed is and vice versa.; the maximum safe operating speed varies with different safety index limits, which can offer reference for the control of the train's running safety under cross winds.
