摘　　要：采用集中质量参数法建立了土压平衡盾构减速器三级行星齿轮传动系统纯扭转动力学模型,模型中考虑了时变啮合刚度、啮合阻尼及传动误差等因素。根据盾构减速器的设计参数,求得了系统的固有频率和振型;使用变步长的Runge-Kutta法求得了传动系统各齿轮的振动位移;计算了各齿轮副的动态啮合力。进行了盾构减速器的振动测试实验,结果表明,理论分析结果与实验数据具有较好的一致性。A pure torsional dynamic model of three-stage planetary gear transmission system of earth pressure balance shield machine reducer is built by using lumped mass parameter method,in which time-varying meshing stiffness,meshing damping and transmission error are considered.According to the design parameters of the shield machine reducer,the natural frequencies and vibration mode of the transmission system are calculated;by using variable step Runge-Kutta integration method,the vibration displacement responses of the transmission system as well as dynamic meshing force of each pair of gear are investigated.The vibration measurement experiment of the reducer is carried out,and the calculated result and experimental data coincides with each other very well.
