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.
