Aim\ In order to make the security and strength be able to meet the demand in the course of high-speed running on the train

the stress during installing on the axis and the wheel and in the process of braking are analyzed. Methods\ The geometrical model is established and the nonlinear finite element analysis about the structure is processed by ANSYS software. Results\ The temperature field and the stress field of the structure are obtained. Conclusion\ The results prove that the wheel structure is reasonable

and some advices are put forward about improving structure.
