摘　　要：根据接触力学理论用有限元法对应用于盾构机主轴承的推力圆柱滚子轴承进行了动态分析,结果表明:由于滚动体各点速度的不同,不可避免的存在滑动摩擦损耗,并计算出轴承的滑动摩擦损耗量;还计算出滚动体与套圈接触“边缘效应”所引起的应力集中等,为研究推力圆锥滚子轴承和对比研究推力圆柱滚子轴承与推力圆锥滚子轴承的接触动力学性能提供基础和参考.The dynamic contact analysis of thrust cylindrical roller bearing used in shields isconducted based on Finite Element Method according to contact mechanics theory.The results show that the sliding friction loss unavoidably existsdue to the speed difference.The sliding friction loss of the bearing is calculated,and the stress concentration caused by contact edge-effect between roller and ring is given.The work of this paper offers a base and a reference to research thrust cylindrical roller bearings in contrast with thrust tapered roller bearings.
