With the vertical contact of wheel tread and top surface of railhead as well as lateral contact of wheel flange and lateral surface of railhead, the mechanical model of wheel and rail is set up. Through the bucket sorting search method based on segment and bi-direction contact manner, the dynamic running simulation in the straight and curve line with 3D rolling contact model is achieved.
