摘　　要：建立一个包含随机齿侧间隙、摩擦、时变啮合刚度等影响齿轮振动因素的行星齿轮系统动力学模型.使用非线性动力学方法对系统进行求解,并分析激励频率对系统的影响.提出修形的主动降噪措施对系统进行改进,重新计算行星齿轮系统的动力学方程.求解并分析激励频率对改进之后系统的影响,并和原始系统得到的结果对比,可以看出修形对于齿轮系统的减振是有效的.A dynamic model of planetary gear system including random backlash,friction,time-varying meshing stiffness and other factors affecting gear vibration is established.The nonlinear dynamics method is used to solve the equation,and the influence of excitation frequency on the system is analyzed.The active noise reduction measures of profile modification are proposed,the system is improved,and the dynamic equation of planetary gear system is recalculated.The influence of the excitation frequency on the improved system is solved and analyzed,and compared with the results obtained by the original system,it can be seen that the modification is effective for the vibration reduction of the gear system.
