Title:
TENSION SYSTEM OPTIMIZATION METHOD FOR SUPPRESSING VIBRATION OF COLD TANDEM ROLLING MILL
Document Type and Number:
WIPO Patent Application WO/2020/020192
Kind Code:
A1
Abstract:
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, and 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.
