Abstract：In order to effectively reduce the possibility of high-speed train derailment and overturning under strong cross wind,and according to the principle of fluid mechanics and the analysis experience about the resistance ability of the high speed train under cross wind,train body section with a better resistance ability of cross wind was innovatively designed based on the existing train top limit and ergonomics principle of interior layout whose speed is greater than 200 km/h.The aerodynamic performance under the 25 m/s crosswind to the high speed train CRH2,CRH3,CRH5 and innovatively design car body were simulated which were based on the finite volume method and CFD software,using simple arithmetic and k-εequation turbulence model of the two dimensional steady incompressible flow N-S equations.Comparing with that three kinds of high-speed trains,the results show that the overturning moment of the innovatively design car body was decreased obviously and the resistance ability of crosswind was better than that of the above three kinds of high-speed trains.
