摘要
基于轧机的实际振动情况,建立了轧机工作辊的单自由度模型,对三倍频颤振进行了分析仿真.根据轧制界面的受力,通过引起负阻尼的公式得出了速度对三倍频颤振的抑制方法.
Based on actual vibration situation of roller,model of single degree of freedom and simulation of three times frequency flutter was established.Suppression method concerning speed on three times frequency flutter was produced by formula about negative damping according to the force of the rolling interface.
