    Abstract
  • Using numerical computation of fluid flow, the coefficients of vertical force, lateral force and rolling moment caused by cross-wind were calculated, which were related to train speed and wind speed. The equation of train stability was derived with the theory of moment balance from the view of dynamics, and the relation between the train's critical speed of different loading conditions and wind speeds was calculated based on the real running. The effects of vertical force, lateral force and rolling moment on the capsize stability were also analysed. The results show that the vertical force is main factor caused by cross-wind, the critical wind speed of empty car is lower than the speed of loading car, and the critical train speed of loading car is lower than that of empty car.
