The application discloses a tension system optimization method for suppressing vibration of a cold tandem rolling mill. The method aims to suppress vibration occurring in a high-speed rolling process of a cold tandem rolling mill, and provides a rolling machine vibration determination index coefficient for effectively determining whether vibration occurs in a rolling machine. The method employs a target optimization function F(X) such that a mean square error between an optimal value ψ0i of the rolling machine vibration determination index and a vibration determination index ψi of each machine frame acquired in an actual rolling process is at a minimum, and such that a maximum value of the rolling machine vibration determination index coefficient of each individual machine frame is also at a minimum, employs a constraint in which an upper threshold ψi+ of the vibration determination index is acquired during a rolling process in an over-lubricated state in which a neutral angle γi coincides with a bite angle αi and a constraint in which a lower threshold ψi− of the vibration determination index is acquired during a rolling process in an under-lubricated state in which the neutral angle γi is half the bite angle αi, thereby ultimately optimizing a tension system of a rolling process of a cold tandem rolling mill.
An iterative method for suppressing vibration of a cold tandem rolling mill, the mill comprising a plurality of machine frames for processing steel strips, by optimizing the inlet tension value and the exit tension value for each of the plurality of frames, where the dimensional and process operational parameters of the rolling mill are defined as follows:
