摘　　要：基于时变啮合阻尼、时变啮合刚度和静态传递误差的考虑,建立了含间隙的弧齿锥齿轮副扭转动力学模型,并采用Runge-Kutta法求解,主要分析时变啮合阻尼和齿侧间隙对系统响应的影响。计算结果表明,系统的非线性振动特性受时变啮合阻尼和间隙的影响较明显。随着阻尼系数和间隙的改变,系统振幅在一定范围内会产生较明显的波动,而且还会出现周期、拟周期和混沌运动以及分岔和跳跃现象等非线性特性。Considering of time-varying meshing damping and time-varying meshing stiffness and static transfer errors, the torsional dynamics model of spiral bevel gear pair with backlash is estab- lished. The Runge-Kutta numerical integral method is then used to solve the model. The dynamic re- sponse of gear system is acquired under the influence of time-varying mesh damping and gear back- lash. The results show that the non-linear vibration characteristics of gear system are affected obviously by time-varying mesh damping and gear backlash . With the change of meshing frequency and backIash, the system amplitude could produce evident fluctuation in a certain range and the non-linear characteristics are observed, such as periodic motion, quasi periodic motion and chaotic motion as well as bifurcation and jumping phenomenon etc.
