- Nonlinear dynamic analysis was performed on a planetary gear transmission system with meshing beyond the pitch point. The parameters of the planetary gear system were optimized,and a two-dimensional nonlinear dynamic model was established using the lumped-mass method. Time-varying meshing stiffness was calculated by the energy method. The model consumes the backlash,bearing clearance,time-varying meshing stiffness,time-varying bearing stiffness,and time-varying friction coefficient. The time-varying bearing stiffness was calculated according to the Hertz contact theory. The load distribution among the gears was computed,and the time-varying friction coefficient was calculated according to elastohydrodynamic lubrication(EHL)theory. The dynamical equations were solved via numerical integration. The global bifurcation characteristics caused by the input speed,backlash,bearing clearance,and damping were analyzed. The system was in a chaotic state at natural frequencies or frequency multiplication. The system tran
