Dynamic contact behavior occurring between wheels and rails while the train running is an unsteady phenomenon and it becomes more complicated when passing through a curve. To examine the mechanism of this phenomenon, the authors developed a dynamic rolling contact tool, called “Wheel/Rail rolling contact simulator”, using a large-scale parallel finite element method. This tool uses the Lagrange multiplier method to calculate the contact force in the normal direction between the wheel and the rail, and it is possible to obtain a precise contact force distribution within the contact surface. In this paper, we reproduce the rolling behavior in the curve section with one bogie model, and discuss the contact behavior occurring in the contact patch of each wheel.
