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 &#x3c8;of the rolling machine vibration determination index and a vibration determination index &#x3c8;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 &#x3c8;of the vibration determination index is acquired during a rolling process in an over-lubricated state in which a neutral angle &#x3b3;coincides with a bite angle &#x3b1;and a constraint in which a lower threshold &#x3c8;of the vibration determination index is acquired during a rolling process in an under-lubricated state in which the neutral angle &#x3b3;is half the bite angle &#x3b1;, thereby ultimately optimizing a tension system of a rolling process of a cold tandem rolling mill.
