摘要
根据某初轧机的结构设计方案,利用大型有限元软件ANSYS,建立了结构分析模型,得出了该轧机机架容易激发的固有频率与振型,以及承受最大轧制力时的变形程度。分析结果显示出机架结构振动大小的分布,确定了该机架的危险截面位置,为轧机机构设计提供了依据。
Based on the structural design scheme for a type of blooming mill, the structural analysis model is established by means of the FEM software ANSYS. The natural frequency and the vibration models, which are easily be provoked, the deformation caused by maximum rolling force are obtained for the frame of the mill. The distribution of vibration of the frame is displayed, and the position of dangerous cross-section is determined by means of the analysis results. The reliable foundations for the frame design of blooming mill are provided in reality.
