文章摘要: During railway vehicle rolling, the interference fitted surfaces between axle and bearing are worn due to fretting. The contact stress is one of the most important factors influencing micro damage. In this paper, the finite element model of axle-bearing interference fitted surfaces was established by using the finite element software ABAQUS. The influence of interference fit tolerance and friction coefficient on the contact stress was investigated. The results show that the interference fit tolerance has an important effect on the contact stress. The contact stress will be increased with the increasing of interference fit tolerance. The maximum stress appears on the contact edge of the fitted surface and stress concentration phenomenon is observed. Meanwhile, the friction coefficient has negligible effect on the contact stress of the fitted surface.
