摘要
以250 t桥式起重机为研究对象,采用有限元分析软件ANSYS对其承轨梁结构进行建模,求得桥式起重机承轨梁的前10阶固有频率和振型,为大型桥式起重机承轨梁的设计提供了参考。
The 250t crane was taken as research object. Its bearing rail beam structure model was built by the finite element analysis software ANSYS. The first 10 natural frequencies and mode shapes were ultimately obtained. It provides reference for large bridge crane rail beam bearing design.
