Abstract： To investigate the nonlinear dynamics behavior of non-circular planetary gear systems， a non-circular planetary gear transmision system was first developed based on the relative motion relationships among system components. Subsequently，a nonlinear dynamics model was established by incorporating critical nonlinear factors including time-varying mesh stiffess，backlash，meshing damping，and excitationfrequency. The dynamics characteristics were quantitatively analyzed through bifurcation diagrams， phase portraits，and time-domain waveforms to elucidate the influence mechanism of various parameters on system vibration response. The results show that the system exhibits complex dynamics behaviors under variations in eccentricity，meshing damping，and excitation frequency. Higher damping coefficients and elevated excitation frequencies are found to enhance system stability，while eccentricity is identified as an effective parameter for sun gear performance modulation.
