The main contents of this paper are as follows:. The dynamic models of stator rotary drive and stator fixed toroidal planetary worm drive system are established. The natural frequencies and modal modes of the two transmission systems under different planetary wheel numbers are obtained. The free vibration characteristics of the two transmission systems in the planetary gear mode and the coupling mode are compared and the variation of the natural frequencies of the two transmission forms with the system parameters is studied. The forced response of the toroidal planetary worm drive under impulse excitation is studied, and the influence factors and rules of the forced response of the stator rotary and fixed stator supertoroidal planetary worm drive system are analyzed. The dynamic model of the electric system of the supertoroidal planetary worm drive is established and the calculation formula of the electromagnetic meshing stiffness is derived and the variation law of the system vibration with the electrical parameters is studied. In this paper, the parameter vibration of the supertoroidal planetary worm drive is analyzed, the meshing stiffness of periodic variation is solved, the frequency domain analysis and the time domain analysis of the parameter vibration of the epicyclic worm drive are completed.
