The Threo-Dimensional Analysis of the Self-Vib rational Characteristics of the 2050mm Hot-Strip Mill Housing by Means of Laser Holographic Interferometry and Finite Element Method

摘要: 根据相似理论,进行了宝山钢铁总厂热轧厂2050热连轧精轧机机座自振特性的三维模拟研究,并应用全息干涉术进行了前三阶主振型分析.本文还进行了三维有限元数值分析与模拟值进行了映照.二者结果是吻合的.

Abstract: According to the theory of similarity, a three-dimensional simulation study on the self-vibrational characteristics of the 2050mm hot-strip finishing mill housing at Baoshan Iron and Steel Complex has been carried out. The analysis of the main vibrational modes of the first three orders has also been done by means of holographic interferometry. In addition, the authors have carried out the numerical analysis of finite elements in three dimensions. The comparison of the results of both analyses (simulation analysis and numerical analysis of finite element) shows that they are consistent.
