Analysis for the wheel-axle interference fits behavior of the high-speed train

Ning Wang

Abstract

The there-dimensional finite element model of the wheel-axle is modeled and the interference fits behabior of the wheel-axle with high-speed is calculated.The wheel-axle contact pressure and the von mise stress of the wheel is analyzed and the wheel-axle interference fits behavior with different speed is compared.The results show that the rotation speed has great influence on the wheel-axle contact pressure.With available magnitude of interference,the material of wheel and axle will present plastic deformation when static and the contact pressure will sufficiently large to transfer the effective torque when the train running at high speed.
