摘　　要：A350和波音787是当今最先进的民机代表,机体结构的复合材料含量高,形成大量的金属与复合材料的混合结构,如翼身对接结构。研究两种机型的翼身对接结构有现实的借鉴意义。阐述了民用飞机翼身对接工艺界面通常的选取范围,图解了两种机型对接工艺界面各自的特点;列举了两种机型机翼壁板对接、机翼梁对接和外翼上壁板中机身对接的结构并加以分析,比较了两种对接结构的优缺点;说明了两种对接结构对翼身装配和总装的影响;对混合结构连接的国内研究状况和设计思路做了阐述。最后总结了两种机型对接结构的特点。A350 aircraft and Boeing787 aircraft are the most advanced representative of modern civil aircraft,which have the relative higher composite material content.The special design forms a large number of hybrid structures between the metal and composite materials such as wing body butt structure.It is of practical significance to study the docking structure of the two models.The design principle on selection range of the wing body docking process interfaces of the civil aircraft is described.The differences and characteristics of the two types of docking process interface are illustrated,and the structures of the two types of aircraft wing panel butt,the wing beam butt and the outer wing panel-fuselage panel butt are analyzed,and the advantages and disadvantages of connection structures of the two aircrafts above are analyzed and compared in this paper.The influence of the two docking structures on wing assembly and final assembly is explained,and the domestic research status and corresponding design ideas of the hybrid structure connection are expounded.Finally,the characteristics of the docking structure of the two models are summarized.
