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. 相似文献
