摘　　要：为了解决在齿轮动力学仿真中啮合刚度的时变性问题,在三维建模软件Solidworks中,通过渐开线参数方程建立了直齿圆柱齿轮装配体模型,将模型导入ANSYS workbench的瞬态动力学模块,用准静态的方法求出了综合啮合刚度,考虑齿轮的惯性效应以及轮齿摩擦力进行齿轮动力学仿真.结果表明,实际情况下综合啮合刚度与理论重合度计算的综合啮合刚度是不同步的.轮齿在进入和退出双齿啮合时振动加剧,轮齿的交替啮合产生冲击力,单齿啮合比双齿啮合振动强烈.In order to solve the time-varying problem of meshing stiffness in gear dynamics simulation,a spur gear assembly model was established via the involute parametric equation using the 3D modeling software Solidworks,the model was imported into the transient dynamics module of ANSYS workbench,and the comprehensive meshing stiffness was obtained with the quasi-static method. The gear dynamics simulation was conducted with the consideration for gear inertia effect and tooth friction. The results show that the comprehensive meshing stiffness in the actual situation is asynchronous with that computed in terms of theoretical contact ratio. When the gear teeth enter into or exit from the double teeth meshing,the gear vibration is intensified. The impact force occurs when the gear teeth meshing alternates with each other,and the vibration of single teeth meshing is more intensified than that of double teeth meshing.
