Abstract：

The dynamics analysis of feed drive system for doubleroller clamping spinning device was carried out, and the dynamic model of the feed drive system was obtained. Then, the multirigid model and the rigidflexible coupling model of the doubleroller clamping spinning device driven by multimotor were simulated by the multibody dynamics software ADAMS and finite element software ANSYS, and the correctness of the established model was verified by comparing the theoretical results with the simulation results of the movement path of clamp and roller head. The simulation process fully considered the nonlinear factors such as equivalent damping, stiffness and friction between slider and guide rail to improve the simulation accuracy. The simulation results of the rigidflexible coupling model show that the feed rate of the roller head fluctuates by ±0.065%, the period is 0.42 s, the feed rate of the clamp fluctuates by ±0.4%, and the period is 0.71 s, which indicates that the elastic deformation of screw affects the motion accuracy of the feed drive system of the device.
