    摘要:

    蒙皮破孔是最典型的飞机战伤形式之一,目前对其抢修的方式主要有纯铆接修理和纯胶接修理,在修复效果或修复时间上存在不足。提出利用胶铆混合方式进行蒙皮破孔修理,采用疲劳试验与有限元分析方法,针对带预置圆形破孔损伤的破孔件、铆接修理件、胶接修理件和胶铆混合修理件进行疲劳性能对比研究。结果表明:相比纯铆接和纯胶接修理方式,胶铆混合连接方式具有最佳的修理效果,混合连接中铆钉作用能有效提高胶层承载并抑制胶层剥离;胶铆混合修理方式与纯铆接相比疲劳性能更优,与纯胶接相比修理时间更短,在金属蒙皮破孔结构的战伤抢修工作中具有良好的应用前景。

    Abstract:

    Broken hold of the skin is one of the most typical forms of aircraft battle damage. At present, the repair methods mainly include rivet repair and adhesive repair, which are insufficient in repair effect or repair time. In this paper, a method of adhesive-rivet hybrid repair was proposed to the skin broken hole. The fatigue test and finite element analysis were used to compare the fatigue properties of four kinds of specimens with prefabricated circular broken hole damage:without repair, riveting repair, adhesive repair and adhesive-rivet hybrid repair. The results showed that compared with the other two repair methods, the adhesive-rivet hybrid repair method has the best repair effect, and the fatigue life is 2.396 times that of the specimen with broken hole; The rivet function in the hybrid connection could effectively improve the bearing capacity of the adhesive layer and inhibit the peeling of the adhesive layer. Compared with the adhesive repair, the peak shear stress of the adhesive layer was increased by 6.3%, and the peak peeling stress was reduced by 23.1%. The adhesive-rivet hybrid repair method has better fatigue performance than riveting repair, and the repair time is shorter than that of gluing repair. It has a good application prospect in the battle damage repair of metal skin perforated structures.
