采用ANSYS有限元软件得到结构的位移模态分析数据,对于简支梁在不同损伤工况下进行了模态曲率分析,研究表明:模态曲率对于简支梁的损伤比较敏感,能准确判断简支梁损伤出现的具体位置,为工程实践提供了理论依据。
The finite element software ANSYS was used to obtain the displacement modal analysis data of the structure. The modal curvature analysis of the simply supported beam under different damage conditions was carried out. The results show that the modal curvature is sensitive to the damage of simply supported beam, The specific location of the beam damage appears, providing a theoretical basis for engineering practice.
