In order to evaluate the contact strength of a type of high-speed train traction motor rotor,in this paper, for the high speed test train traction motor under the five working conditions, Based on the established motor rotor 3D model, NX.Nastran environment, the contact pressure between rotor and lamination is analyzed by the finite element and got the stress intensity distribution on the rotor. The five working condition include starting, constant work starting condition, rated, short circuit condition, the highest speed condition. The result shows that for the high speed tractor motor, in the starting conditions, and won't appear rotor shaft and laminated relation between slip. The finite element method is useful to do the contact strength analysis, and thus to improve the design efficiency, increase the reliability of the product, and lay the foundation for the latter design optimization.
