The torsional vibration model of main drive system for 6-high cold rolling mill was established. Calculation formula of torque amplification factor (TAF) of main drive system was put forward when the clearance exists or not. The TAF-curve, changing by the biting time of blank, was drawn, and whether torsional vibration could cause mechanical failure in weak link of main drive system was judged. The TAF variation with the biting time of blank was analyzed when the clearance exists. The method to reduce TAF was proposed before the clearance was eliminated, and the effect caused by the impact on main drive system was alleviated.

Using torque telemetry system to test the mechanical drive system of rolling mill,it is found that the torsional vibration and current signal in the electric drive system have the same obviously vibration frequency. The model of cycloconverter, synchronous motor and mechanical drive system of rolling mill are built and analysed by Matlab/Simulink and ANSYS.The simulation results show when the harmonic torque frequency and the torsional vibration natural frequency of for mechanical drive system are equal or close, the strong torsional vibration arouse It is proved that the convertor output current harmonics can induce the electromechanical coupling vibration of main mechanical drive system under the certain conditions.
