摘　　要：预测桥式起重机主梁疲劳寿命,需判断主梁应力集中区域,以期为确定应变片检测位置提供理论指导。使用ANSYS Workbench对50/10t桥式起重机主梁进行多工况有限元分析,得到主梁各工况应力云图。分析结果表明,最大应力出现于主梁两端腹板与下盖板连接处以及下盖板两端弯曲处,这些区域易发生疲劳受损。To forecasting fatigue life of the bridge crane girder,it is necessary to determine the girder stress concentration regions,which could provide theoretical guidance to determine the strain gage measurement position.In this paper,ANSYS Workbench is used to carry out finite element analysis for the 50/10 tbridge crane girder to get the stress nephograms under various conditions.The results show that the maximum equivalent stress locates at the connections between under cover and webs of the girder ends,and bends in the undercover ends,which areas are prone to fatigue damage.
