摘　　要：铁道车辆平稳运行过程中,轴承内圈和后挡的接触面会产生微振磨损。本文利用实物轴承进行磨损试验,通过测试轴承内圈和后挡间的接触面压力,阐述了微振磨损的产生机理,并提出了相应的防范措施。During the stable running of rolling stock, fretting may occur at the contact surface between inner ring and backing ring of bearing. Through the wear test on full-scale bearing and measurement of the contact pressure between inner ring and backing ring of bearing, the generation mechanism of fretting is elaborated and the corresponding preventative measures are proposed.
