Abstract A torsional vibration damper control device is introduced for the torsional vibration phenomenon of the rolling mill main drive system under the sudden load of biting steel. Establishing torsional vibration suppression model of motor and torsional vibration damper. The characteristic parameters of the damper are designed. The inertia ratio, the tonal ratio and the damping ratio of the damper are obtained. Using the fixed point theory, the optimal tuning ratio and damping ratio are obtained. By comparing the time domain characteristic curves before and after adding the torsional vibration damper, it is concluded that the damper can reduce the vibration amplitude; By adjusting the inertia ratio, torsional stiffness and damping coefficient, the influence of different parameter changes on the amplitude-frequency characteristic curve of the rolling mill main drive system is obtained. Appropriate increase of inertia ratio μ can reduce the vibration amplitude, increasing the torsional stiffness Kd can reduce the unstable region of the system, increasing the damping coefficient Cd can effectively reduce the system torsional vibration amplitude. Therefore, selecting the appropriate parameter values can effectively improve the stability of the rolling mill system.
