摘　　要：为探究齿轮变位对啮合刚度的影响,采用两种不同方法计算齿轮啮合刚度:一是运用Pro/E二次开发对齿轮进行参数化建模,并将齿轮模型导入Abaqus软件进行有限元仿真计算,根据计算结果得出不同变位系数齿轮的时变啮合刚度曲线;二是基于能量法的解析法计算得出时变啮合刚度曲线。结果表明,在一定范围内,齿轮啮合的重合度随齿轮变位系数的增大而减小,齿轮的平均啮合刚度随齿轮变位系数的增大而减小。In order to explore the influence of gear modification on the meshing stiffness,two different methods are used to calculate the gear meshing stiffness.First,the gear is parametrically modeled by Pro/E secondary development,and the gear model is imported into Abaqus software for finite element simulation calculation.The time-varying mesh stiffness curve is obtained through data processing.Second is based on the energy method of the analytical method to calculate the time-varying mesh stiffness curve.The results show that within a certain range,the coincidence degree of gear meshing decreases with the increase of gear displacement coefficient and the average meshing stiffness of the gear decreases as the gear displacement coefficient increases.
