摘　　要：针对1700四辊带钢轧机振动问题,利用大型有限元软件ANSYS,建立机架的结构分析模型,得出该轧机机架容易激发的固有频率和振型;并利用结构力学理论对典型模态进行了验证。为轧机机架设计及抑制轧机振动提供了依据。Aimed at the vibration problem of 1700 four rollers strip mill,by using the large FEM software,structure analysis model of mill frame was established;and the natural frequency and the vibration models which are easily be excited were obtained.By using structural mechanics theory,the typical model are validated,which provides reference for the design of mill frame and restraining mill vibration.
