基于ANSYS的龙门起重机主梁力学性能分析

Analysis of the mechanical properties of gantry crane based on ANSYS

采用传统的设计方法在对龙门起重机箱形主梁进行设计时,存在对主梁的受力分析不彻底,结果不准确等问题,影响龙门起重机的使用性能。笔者采用有限元方法,对主梁进行有限元建模,分别对载荷位于跨中、悬臂端时进行受力分析,得到了主梁静载荷的变形量,为龙门起重机的结构设计提供了一种行之有效的分析方法。

While the box girder of gantry crane is designed by traditional designing method,the stress of box girder can not be usually analysed intensively,which results in the inaccurate results and affects the operationperformance of gantry crane.In this paper,the finite element model of box girder is built with finite element method,and the separate stress analysis is carried out while the load is acting on the middle of the main girder and the cantilevered end.Finally the amount of deformation of static load acting on the main girder is obtained. The results provide an effective analysis method for the design of gantry crane.
