Abstract: A vibration suppression method and system of a rolling mill roller assembly based on a vibration damping device are provided. The vibration suppression method includes: obtaining a first amplitude-frequency relationship during a vibration process of a rolling mill roller assembly vibration suppression system; based on the first amplitude-frequency relationship, determining two time domain relationships and two second amplitude-frequency relationships by a simulation analysis; based on the two time domain and relationships two second amplitude-frequency relationships, adjusting parameters of the vibration damping device until a vibration displacement of the rolling mill roller assembly vibration suppression system is less than or equal to a vibration displacement threshold. And provides a new solution for the stability control of the rolling mill, and ensures the reliability and stability of the vibration suppression of the rolling mill.

Abstract: The present invention belongs to the technical field of control for rolling mill vibration, and particularly relates to a control device, system and method for vertical-horizontal coupling vibration of a corrugated rolling mill. The control device includes a housing; a vibration-absorbing container is arranged in the housing; a steel ball particle group is placed in the vibration-absorbing container; a left side of the vibration-absorbing container is connected with one end of a return spring; the other end of the return spring is fixedly connected with a third base; the third base is fixedly mounted on a third sliding block; and the third sliding block is slidably arranged on a third linear guide rail.
