摘　　要：大型步履式架桥机的主梁是架桥机工作时的主要受力构件,通过对架桥机主梁结构进行有限元模拟,寻找能确定损伤位置及大小的关键参数,同时选择有限元分析结果中容易损伤的位置进行应力测试及无损探伤,提升了检验工作效率,为架桥机的在线检测质量提供相应保障。The Girder in Bridge Erection Machine is the main stress component of the bridge erecting machine.In this paper,through the finite element simulation of the main beam structure of the bridge erecting machine,the key parameters that can determine the location and size of the damage are found.At the same time,the stress test and non-destructive testing are carried out at the location prone to damage in the finite element analysis results,which improves the inspection efficiency and provides the corresponding quality for the on-line inspection of the bridge erecting machine Guarantee.
