摘　　要：结合近年来铁道车辆数次构架裂纹故障,根据国际焊接学会标准,利用有限元计算结果,对某出口窄轨动车组转向架构架关键部位典型焊接接头形式进行了疲劳损伤评估。Combined with several troubles of cracking in rolling stock bogie frames in recent years,according to the standard of International Institute of Welding,with use of the finite element calculation result,the fatigue damage evaluation is made for the type of typical welding joints at key parts of bogie frames for a certain type of exported multiple units with narrow gauge.
