Stability Analysis of Nonlinear Self-excited Vibration in Cold Rolling Main Drive System

摘要：

　　A nonlinear self-excited vibration model of main drive system in cold rolling is established.The mechanism of torsional vibration in main drive system stability is discussed within multiple scale method as well as Hopf bifurcation theorem.Then,the periodic solutions and condition of Hopf bifurcation are derived and the influence by subcritical/supercritical bifurcation is analyzed.Based on the simulation experiments with actual industrial data,the previous theoretical analysis and nonlinear model have been testified.
