Furthermore, many experiments and theoretical studies have shown that the lubrication condition in the roll bite is one of the most important factors affecting the rolling mill vibration. Yarita et al. 1 pointed out that lubrication defects may cause vibration, and better lubrication conditions can suppress vibration effectively.
1) The stability domain of the rolling mill system is enclosed by the instability critical line of vertical vibration modal, torsional vibration modal and horizontal vibration modal. 2) Under different conditions, the system Hopf bifurcation induced by lubrication conditions change between roller and the rolled pieces can cause system instability with different vibration modals.
Based on vibration problems of a six roller cold rolling mill, hydraulic-machinery coupling vibration system dynamic model of the 2180mm 4-stand tandem cold rolling mills was built integrated the software of MATLAB and ADAMS and simulated. The simulation result was consistent with that of the field test data revealed by rolling mill vibration.
