摘　　要：首先利用赫兹理论,计算出同一角接触球轴承在相同工况、不同内外沟道曲率下的最大应力。并运用ansys参数化语言APDL建立角接触球轴承的三维有限元模型,且模型考虑了径向游隙和轴向游隙。再利用Ansys/LS-DYNA对角接触球轴承进行预紧载荷的加载、径向力与轴向力的加载和内圈转速的加载。并将理论分析与有限元分析进行对比研究,从而验证了有限元分析的正确性。最后,得出角接触球轴承在不同内、外沟道曲率半径下的最大应力,为角接触球轴承沟道曲率半径的选择提供科学依据。Firstly the theory of Hertz was used to calculate the maximum stress of same angular contact ball bearings in the same condition and different internal and external channel curvature radius. And ANSYS APDL parametric language was used to establish three-dimensional finite element model of angular contact ball bearing and the model considers the radial clearance and axial clearance. ANSYS / LS-DYNA was used to load pre-tightening force,radial force,axial force and inner rotation on bearing.And comparative study on the theoretical analysis and finite element analysis was made to verify the validity of the finite element analysis. Finally,maximum stress of angular contact ball bearing was obtained in the different internal and external channel curvature,in order to provide scientific reference for the selection of channel curvature radius of angular contact ball bearings.
