Abstract：

The corrugated roll mill often vibrates due to the influence of roll shape curve in the rolling process of composite plate, and the vertical vibration of roll system in the corrugated roll mill affects the stability of rolling process. For the corrugated roll mill, the vertical vibration model of the rolling mill with four degrees of freedom was established. Then, the rolling processes of corrugated roll and flat roll were simulated by finite element software ABAQUS respectively, and the change of rolling force in the rolling process was compared and analyzed. Furthermore, the natural frequency of roll system in the corrugated roll mill was solved, and the dynamic response of roll in the rolling process with corrugated roll and flat roll was simulated and analyzed by analysis module Adams/Vibration. The results show that because the surface of corrugated roll is waviness, when rolling composite plate，the rolling force of corrugated roll is larger than that of flat roll with the great rolling force fluctuate, and the vibration in vertical direction is more obvious.
