Abstract: The vibration characteristics and mechanisms of ring rolling process were analysed, a physical vibration model for the ring rolling process was proposed, and the dynamical vibration equations were established. Based on the contact state between ring and roller, the conditions of linear and non-linear vibrations corresponding to small and large amplitude respectively were determined, and the related stability conditions of vibration were derived. The factors which influence the vibration stability of ring rolling were discussed, which provides theoretic basis for the design, prediction and control of steady ring rolling.
