Abstract:A dynamic model of compound planetary drive system was built and multiple nonlinear factors such as time variable meshing stiffness, meshing clearance and meshing error were considered. Influence to the frequency coupling of compound planetary drive system caused by different internal non-linear incentives and external incentives such as time-change torque input, constant value torque input was analyzed. Harmonic balance method was adopted,the coupling resonance of the drive system was analyzed which consider low frequency, high frequency and its coupling caused by internal, external and its coupling incentives. The results show that, when the driving torque is constant, the main frequency component of both meshing force of the gear and shear force of the shaft are meshing frequency and multi-frequency; when the driving torque is time-variable, meshing related frequency of the meshing force is the main frequency component under all the rotate speed, and the main frequency component change from meshing related frequency to main order frequencies of the engine; in the system resonance speed belt, caused by tooth frequency resonance and it’s coupling frequency resonance speed are mainly concentrated in middle-low speed condition, the incentive of resonance caused by engine speed mainly focused on high speed.
