摘要
对桥式起重机结构进行了有限元模态分析,得出了各阶模态下主梁的固有频率和固有振型,找到了主梁振动中的危险区域,为设计和改造提供了理论依据。
Finite element modal analysis of the structure of an overhead traveling crane is carried out.The inherent frequencies and vibration modes of the crane s main girder are obtained,and the dangerous areas of the main girder are found.It provides a theoretical basis for girder design and retrofit.
