In order to reduce the deflection vibration of ring during the rolling process and achieve the smooth rolling of ring, a VDISP subroutine was written based on software ABAQUS to realize the control of guide roller in the numerical simulation, and according to different guide roller control methods, four modes were established respectively, namely, no guide roller, guide roller fixed, guide roller follow-up and subroutine controlled guide roller movement. Then, using the control variable method, the deflectionl-time curve, size-time curve and energy-time curve of the above models were analyzed. The results show that the established adaptive control system for ring rolling can effectively reduce the deflection vibration problem during the ring rolling process and improve the stability of the ring rolling process. The deflection amount is basically controlled within the range of 0.4 mm, and most of the energy generated during the rolling process can be used for the rolling and deformation.
