摘　　要：为对保持架动态特性进行分析,基于ABAQUS建立角接触球轴承有限元模型,通过施加不同的转速和载荷进行动力学仿真,从保持架质心运动轨迹和质心涡动速度偏差比两方面对其动态特性进行分析。结果表明:轴承仅承受轴向载荷时,保持架稳定性随轴向载荷增大先提高后降低;同时承受轴向载荷和径向载荷时,轴向载荷和转速增大可提高保持架稳定性;径向载荷增大时,保持架稳定性降低,且径向载荷对保持架动态特性影响比轴向载荷大。In order to analyze dynamic characteristics of cages,the finite element model of angular contact ball bearings is established based on ABAQUS.The dynamic simulation is carried out by applying different rotational speeds and loads,and the dynamic characteristics of cages are analyzed from two aspects:the trajectory of center of mass for cages and deviation ratio of vortex velocity of center of mass.The results show that when bearing subjected to pure axial load,the stability of cages increases first and then decreases with increase of axial load;when the axial load and radial load are simultaneously applied,the increase of axial load and rotational speed improve stability of cages;when the radial load increases,the stability of cages decreases,and the radial load affects dynamic characteristics of cages more than axial load.
