本文在对上钢五厂750初轧机工作机座进行实测的基础上,首次对横向振动问题做了探讨性的分析,并在分析一系列外扰因素之后,找出其主要外扰因素,即突加(突卸)荷载的横向分量和压下系统的不平衡质量。提出了从避振观点来选择压下装置的机电系统的必要性,并对750初轧机工作机座提出改进措施。 Based on the measurement of the working stand of the 750 initial rolling mill in the No.5 steel plant of Shanggang Iron and Steel Co., Ltd., this paper firstly analyzes the horizontal vibration problem for the first time and finds out the main external disturbance factors after analyzing a series of external disturbance factors Transverse (unloaded) transverse component of the load and the unbalanced mass of the system. The necessity of selecting the electromechanical system of the pressing device from the point of view of vibration isolation is put forward and the improvement measures for the working stand of 750 initial rolling mill are put forward.
