单钩桥式起重机主梁设计

Design of Main Beam in the Single-Hook Bridge Crane

介绍了桥式起重机主梁设计的计算方法及校核过程。应用有限元软件建立主梁三维模型,并针对主梁进行了静力学分析。为保障主梁结构的可靠性,将主梁与端梁装配成桥架,建立了桥架整体模型,并进行了静态分析和模态分析,在确认桥架设计合理的基础上提出了改进方案。

In this paper,the calculation method and checking process of the main beam design in the bridge crane are introduced,where the finite element software is used to establish a three-dimensional model and a static analysis is carried out for the main beam.In order to ensure the reliability of the structure,the main and the end beams are assembled into a bridge frame.With an overall model of the bridge frame established,the static and modal analysis are made,and an improvement plan is proposed based on the reasonable design of the bridge frame.
