Study on Non-linear Twist Vibration of Main Transmission System for Vertical Rolling Mill

摘要

Four degrees of freedom non-linear dynamical model on vertical vibration system of the 4200 vertical rolling mill had been established. Numerical results of vibration equations were figured out by Matlab software. Phenomenon of quasi-periodic and chaotic vibrations of the vibration system was discussed using the method of Phase graph and Poincare section.
