| الوصف: | The torsional vibration is a technical problem during the rolling process, which seriously affects rolling stability and production efficiency. In order to study the influence of axis deviation of the rolling mill transmission system on torsional vibration, a reasonable dynamic model can be established to explore its dynamic characteristics. In this paper, considering the periodic excitation caused by the axis deviations and the torsional torque change under the torsional vibration, the nonlinear dynamic model of the transmission system was established. The simulation results show the energy input to the main transmission system approximately periodically through obtaining the drive energy of the rolling mill motor by the equivalent eccentric mass. The dynamic change of tension and friction moment of the strip is caused by the torsional vibration of the transmission system, which leads to an unstable energy conversion process in the rolling interface. Through the monitoring experiment data by taking the 7-stand tandem hot rolling mill of Chengde Steel Co. for example, the theory reliability was further verified. All these research results are significant to solving the torsional vibration problem of rolling mill drive system with axis deviations and provide references for the operation in the strip production process. |
