摘　　要：针对国外铁路货车市场普遍使用的AARM1001标准,以罐车为例开展了500万公里、空重比为1∶1状态的车体焊缝全节点疲劳评估研究工作。文中介绍了AAR标准疲劳寿命计算方法及载荷谱、焊接接头在nCode软件中的使用方法,通过手动计算与nCode软件计算结果对比,证实了全节点疲劳评估方法的可行性。According to the AAR standard co mmonly used in the foreign railway freight car market,taking tank car as an example,the fatigue evaluation of the whole joint of the weld seam of the car body of 5 million kilometers with empty weight ratio of 1:1 was carried out.This paper introduces AAR standard fatigue life calculation method,load spectrum,welding joint in nCode software application method.The comparison of manual calculation and nCode software calculation resuls demonstrated the feasibility of the method.
