Abstract In order to solve the intensive vibration problem during thin products rolling， comprehensive vibration test on the stand F2 of 2 160 mm hot tandem rolling mill system has been carried out in this paper. First， the vibration phenomenon was introduced and the type of this vibration was analyzed. Then， a new rolling interface friction model was established by considering the dynamic characteristic of the rolling interface， which could characterize the positive and negative damping effect of the interface. More explicitly， the coupled vibration model with torsional vibration and horizontal vibration was established based on the above model with different movements between the upper and lower roll system. Based on the built model， the self-excited vibration was simulated in the hot rolling. It is found that the upper and lower work roll moved reversely in both torsional and horizontal directions， and the vibration frequency was the first-order natural frequency of torsional vibration， which was consistent with the measured phenomenon. Finally， the influences of the rolling parameters on the self-excited vibration were analyzed， and the corresponding feasible suppression measures of vibration were proposed.

Key words： Vibration test Coupled vibration Friction model Self-excited vibration Move reversely
