Abstract：

With the deeper research on vibration of cold rolling roll, it was found that most of types of the vibration happened on the work rolls was the coupled vibration. Firstly, the simplified vibration model of the main drive system and the rolls were established, and their natural frequencies were calculated by software Matlab. Then, the dynamic simulation of rolls was conducted by software Adams, and interfering force and torque in three times vibration frequency were added during the simulation process. The simulation shows that without the outer interference, self-excited vibration occurs in cold rolling mill because of the friction between the rolls; for the six rolling mill, the horizontal vibration of the middle roll has impacts on the vertical vibration and the torsional vibration of work rolls. When the vertical vibration and the torsional vibration occur at the same time, the vibration of work rolls shows the characteristics of other vibrations.
