摘要
建立包含时变刚度和齿侧间隙的单对齿轮系统振动模型,推导综合考虑时变刚度、齿侧间隙、传递误差等非线性因素的振动微分方程。运用四阶Runge-Kutta方法计算系统在无冲击、单边冲击和双边冲击状态下,系统参数、载荷参数对系统振幅及稳定性的影响。数值仿真表明:考虑时变刚度、齿侧间隙等非线性因素时齿轮系统具有复杂的振动特性。
Time-varying stiffness and tooth backlash vibration model is set up and the vibration differential equations are deduced via comprehensively taking time-varying stiffness,tooth backlash and dynamic transmission error nonlinear factor into consideration.Non-impact,single-impact and double-impact are numerically simulated by fourth-order Runge-Kutta method.The effects of system parameters and load parameters on the system of the amplitude and vibration stability are calculated.The simulation results show that： gear system exhibits complex vibration behaviors in considering time-varying stiffness and tooth backlash non-linear factors.
