摘　　要：建立了2K-H人字齿行星齿轮传动系统平移-扭转耦合非线性动力学模型,模型中考虑各构件的支撑刚度,事变啮合刚度和安装误差激励等影响因素。利用当量啮合误差定义,推导了各构件的安装误差在啮合线变长方向的当量啮合误差;分析计算了各构件间的相对位移,根据牛顿第二定律推导系统运动微分方程,采用傅里叶级数法求解系统动力学方程,获得系统的传动误差,分析了安装误差对系统传动误差的影响。A translation- torsional coupling nonlinear dynamic model of 2K-H herringbone planetary gear train is presented. The influ- encing factor of component bearing stiffness, time-varying mesh stiffness, and installation error incentives and so on are considered in the model. The definition of equivalent mesh error is used to deduce installation error of all components in the direction of the mes- hing line longer equivalent mesh error and the relative displacement between components is analyzed and calculated. According to Newton＇s second law system movement differential equation and through the dynamics equation by Fourier series method, the trans- mission error of the train is acquired and the impact of installation error on transmission error is analyzed.
