Research on Finite Element Model of Wheel-Rail Contact Hai Zhang1,a ，Xiaoyi Hu2,b, Fengtao Lin1,c, Xinjian Zhou1,d 1Mechanical and Electrical school, East China JiaoTong University, Nanchang, 330013，China 2Railway Science & Technology Research & Development Center, China Academy of Railway Science，Beijing, 100081，China.
At this time, the grid element keeps fixed and material flow within the grid which effectively simulates the wheel-rail rolling contact.
Wheel model describes the spatial grid with Euleria method in order to achieve separation of grid movement and material movement; rail model describes the spatial grid with Lagrangian method in order to achieve together with the mesh and material movement.
