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。
According to the standard of International Society for Welding (IUA), the fatigue damage assessment of the typical welded joints of the key parts of the bogie frame of an export narrow-gauge track motor vehicle is carried out by using the finite element calculation results.
