Undesirable vibration and chatter are commonly recurring problems in process of thin plate rolling. The traditional approaches to control chatter were to improve lubrication conditions or to be equipped with chatter monitor as a warning system, for instance. But the both methods are not always effective. Then, this paper deals with new approach to control chatter vibration in 4-high tandem cold mill. The flow of approach methods are as follows; (1) The theoretical model is constituted to simulate the vibration behaviors of the 5-stands continues cold rolling mill under various operating conditions. (2) Some approaches to control chatter are considered and the effect of each method was simulated using the theoretical model. (3) The effect of the tuned mass damper as the device to control chatter in the tandem cold mill was evaluated numerically. The results were good agreement with the experimental ones of the practical mill.
