摘　　要：文章将油膜对高速轴承动力学性能的影响简化为对轴承动态刚度、摩擦系数和阻尼的影响,基于Hertz接触理论和弹性流体动力润滑理论,建立滚子与滚道、保持架间的作用力模型,在此基础上运用仿真软件Adams对高速轴承进行动力学分析,探讨高速轴承在一定工况下的运动性能,为高速轴承的优化设计提供参考依据。The effect of oil film on the dynamics performance of the high-speed bearing is simplified as the effect on the dynamic stiffness,damping and friction coefficient of the bearing.The force model among rollers,raceway and retainer is established based on Hertz contact model and elastohydrodynamic lubrication theory.The dynamics analysis of the high-speed bearing is carried out by using the simulation software Adams, and the kinetic performance of the bearing under certain working conditions is discussed.The study could provide references for the optimal design of the high-speed bearing.
