Study on Torsional Vibration of Six High Cold Rolling Mill

Abstract

Aiming at the quality problems caused by vibration in a cold rolling mill of a steel mill. The mechanical model and mathematical model of the main drive system of six high cold rolling mill are established based on the F4 frame which was the strongest vibration. The natural frequencies is calculated by using MATLAB. On this basis, the simulation analysis of damping, clearance and stiffness in the main drive system of rolling mill has been carried out. It is found that the relationship between damping, clearance, stiffness and torque amplification factor which provides an important theoretical reference for the structure design of the rolling mill.
