摘要

建立了含时变啮合刚度、齿侧间隙与轴承间隙、综合啮合误差以及负载激励的人字齿行星齿轮传动系统弯-扭-轴耦合动力学模型，研究了系统的周期运动和分岔。通过数值仿真，得到了系统全局分岔图、均载系数、相图和时间历程图，识别了系统的啮合状态。结果表明，系统的最佳载荷分布效果发生在较低啮合频率周期1振动时，外啮合

与内啮合

均处于完全啮合状态。随着啮合频率增大，系统动态啮合力增大，均载系数变大，系统在周期振动相互演变过程存在Hopf分岔、实擦边分岔和周期倍化分岔等分岔。

Abstract

A bending-torsion-axis coupling dynamic model of herringbone tooth planetary gear transmission system under time-varying meshing stiffness

tooth-side clearance and bearing clearance

integrated meshing error and load excitation was established

and the periodic motion and bifurcation of the system were studied. The global bifurcation diagram

load sharing coefficient

phase diagram and time history diagram of the system were obtained by numerical simulation

and the meshing state of the system was identified. The results show that the optimal load distribution effect of the system occurs in the periodic 1 when the vibration of the mesh

ing frequency is low

both the external

and internal

meshing are in the state of complete meshing. With the increase of meshing frequency

the dynamic meshing force and load sharing coefficient of the system increase

and there are Hopf bifurcation

the real-grazing bifurcation and periodic doubling bifurcation in the process of periodic vibration mutual transition.
