摘要

The model of the roll system vibration is usually limited to a one-dimensional or two-dimensional translation. In reality, however, the roll system also has a rotation behavior due to the uneven force distribution on the roll body. So the vibration, especially in rolling the wide steel strip, should perform a swing behavior, which consists of rotation and translation. In this paper, the experiment phenomena of plant vibration are analyzed, and the influences of roll system vibration on the rolling process are studied. A swing dynamic model of roll system is established considering the dynamic characteristics of the hot rolling process, the uneven force distribution on the roll body, and the coupling relationship between the horizontal and vertical vibration of the work roll. Through the numerical simulation, the natural characteristics of roll system swing are analyzed, the vibration responses of roll system swing are simulated with the arc tooth gear meshing impact force, and the stability of roll system is studied.
