为研究各参数对面齿轮传动系统动态特性的影响，建立了包含齿侧间隙、传动误差、时变啮合刚度、阻尼、支承和外激励等参数的系统弯扭耦合非线性动力学模型，结合非线性动力学数值分析理论求解并得到了系统在不同参数下的分岔特性。计算结果表明，增加齿侧间隙、时变啮合刚度和传动误差会导致系统动载荷明显增大，而增加啮合阻尼则能有效降低系统的动载荷。

In order to study the influences of different factors on nonlinear dynamics of face-gear transmission system, a nonlinear dynamic model is presented. This model includes backlash, general transmission error, time-varying meshing stiffness, meshing damping, bearings and external load, etc. Based on numerical analysis theory of nonlinear dynamics, the equations are solved and the bifurcation characteristics with different parameters are obtained. And the calculation results show that increasing the backlash and time-varying meshing stiffness will augment the dynamic load of system, but increasing the mesh damping will reduce the dynamic load effectively.
