摘　　要：基于拟静力学建立角接触球轴承受力平衡方程,对轴承动刚度进行数值求解。并以某角接触球轴承为研究对象,分析轴承转速、球材料对轴承动刚度的影响,结果表明:随转速增大,轴承轴向和径向刚度先减小后趋于稳定;球材料变化时,轴承轴向和径向刚度随转速的变化曲线也随之改变,但总体趋势相同。The force equilibrium equation of angular contact ball bearing is established based on quasi-statics,and the dynamic stiffness of the bearing is solved numerically.Taking an angular contact ball bearing as a research object,the influence of rotational speed of the bearing and material of balls on dynamic stiffness of the bearing is analyzed.The results show that with the increase of rotational speed,the axial and radial stiffness of the bearing decrease first and then tend to be stabilized.When material of balls changes,the axial and radial stiffness of the bearing change with rotational speed,but the general trend is same.
