摘　　要：对汽车传动系统中的三枢轴式等速万向节不同工作夹角进行强度分析,得到不同夹角下各零件的接触应力及外壳轴段应力分布;并将仿真结果与试验进行对比,验证仿真的合理性与准确性。结果表明:在设计夹角范围内,万向节各零件接触应力满足设计要求;接触应力随工作夹角增加而增大,但增加幅度不大;外壳轴下端应力水平较低,且不同夹角下无明显变化,可以优化该处结构,以减轻万向节质量。该研究结果可为三枢轴式等速万向节设计优化提供指导。The strength analysis of different working angles of three-pivot constant velocity joints in automotive transmission system is carried out,and the contact stress of each part under different angles and the stress distribution of the shaft section are obtained.The simulation results are compared with the test results to verify the rationality and accuracy of the simulation.The results show that the contact stress of each part of the universal joint meets the design requirements within the range of design angle;the contact stress increases with the increase of the working angle,but the increase is not large.The stress level at the lower end of the outer casing shaft at different angles is lowand there is no significant change,and this structure can be optimized to reduce the weight of the universal joint.The results of this study can provide guidance for the design optimization of three-pivot constant velocity joints.
