应用激光全息干涉术及有限元法对2050热连轧机机座自振特性的三维分析

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.     

The three-dimensional analysis of the self-vibrational characteri-stics of the 2050mm hot-strip mill housing by means of laser holographic interferometry and finite element method

According to the theory of similarity,a three-dimensional simulation study on the self-vibrational characteristics of the2050mm hot-strip finishing mill housing at Baoshan Ironand Steel Complex has been carried out.The analysis of the main vibrational modes of thefirst 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 analysisof finite element)shows that they are consistent.
