| Abstract: | According to the theory of similarity, a three-dimensional simulation study on the self-vibrational characteri-stics 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 by means of holographic interfermetry has also been made. In addition, the authors have carried out the numerical analysis of finite elements in three dimensions. The co-mparison of. the results of both analyses (simulation analysis and numerical analysis of finite elements) shows that they are consistent. |
