在研究轧钢机轧制过程中因打滑等因素而产生的自激振动时，本文考虑了因连接轴转动而出现的运动边界问题，提出了一个新的力学模型，建立了具有运动边界问题的运动微分方程。所得到的结论可以应用在轧钢生产之中 In the study of self-excited vibration due to slippage and other factors during the rolling process of the rolling mill, this paper considers the motion boundary problem caused by the rotation of the connecting shaft and proposes a new mechanical model to establish the motion with motion boundary problem Differential equations. The conclusions can be applied to the production of rolled steel
