Abstract: In this paper, completes the selection of preliminary Reactive Powder Concrete (RPC) wind barriers, and on the basis of the theories of the computational fluid dynamics ( CFD), relying on the model-building and analysis platform of FLUENT, 3D models of trains under crosswind with and without wind barriers are built. From the calculation results of the pressure distribution,path lines and aerodynamic forces of model trains under 3D turbulence flows ,the stability of trains under crosswind is analysed ,and the effects of the wind barriers on traffic safety of trains are discussed.The results show that rationa1 design of the wind barriers is able to improve the traffic safety of trains.
