摘　　要：本文以某发动机外部调整片为设计优化对象,结合科研试飞结果,对外部调整片飞行中的载荷情况进行了模拟,分析了裂纹及脱开故障原因。在外部调整片损伤原因定位基础上,针对外部调整片受力薄弱环节提出了优化设计方案,采用仿真对比分析方法论证了优化方案的有效性。This article takes the external adjustment flap of an engine as the design optimization object with consideration on the results of scientific-research flight tests to simulate the load situation of the external adjustment flap during flight.It analyzes the causes of cracks and detachment faults.It proposes an optimization design scheme for the weak stress link of the external adjustment flap based on locating the damage on the external adjustment flap.The effectiveness of the optimization scheme has been demonstrated through simulation comparative analysis.

关 键 词：外部调整片 主动片 从动片 优化设计
