轧钢机机架有限元分析及优化设计

Finite element analysis and optimization of rolling mill

根据某1700粗轧机结构设计方案,使用有限元分析软件COSMOSWorks,建立了结构分析模型。通过对模型的计算分析,得出了该机架承受最大轧制力时最大应力所在位置和应力分布规律。根据分析结果,对其进行优化设计。最后对其进行强度和刚度校核,验证其满足使用要求。

Based on the structural design scheme for a type of 1700 Rolling mill housing,the structural analysis model is established by means of the FEM software COSMOSWorks. Through analytical calculation for mechanics model,the large stress location and stress distributing disciplinarian is found. According to the results of the analysis,optimal design is done for it.At last,through checking strength and stiffness,it is proved that the mill meets the application requirements.
