摘　　要：飞机起落架构件容易发生疲劳损伤。探讨了磁记忆检测技术在起落架构件疲劳试验中应力集中部位检测的应用。可以预计 ,该方法将在构件的疲劳分析。Fatigue impairment is apt to occur in landing gear of airplane. The application of magnetic memory testing (MMT) to measure stress concentration in fatigue trial was studied. It was predicted that MMT would play a leading role in fatigue analysis, life determination of equipment and design of structure and technology.

关 键 词：起落架 磁性检验 磁记忆材料 疲劳试验 飞机 应力集中
