摘　　要：外翼、中央翼的壁板对接结构设计是飞机设计的重要环节之一,不同的对接方式其传力方式不同,对飞机的使用寿命、装配工艺都会产生重大影响。通过对飞机外翼、中央翼对接结构的传力特点的分析,设计了两种不同的上下壁板对接方案,然后运用Altair HyperWorks软件对对接结构进行了有限元分析,得出了较好的对接结构并进行了材料选择,最后运用OptiStruct软件进行了结构尺寸优化和减重分析。The structure design of outer wing and center wing＇s panel is one of the important steps of the aircraft design. The different fitting way decided the power transmission in a different way, it is a significant impact to the use of aircraft life and assembly process. Analyze the force transmission characteristics of fitting structure on aircraft＇ s outer wing and center wing , two fitting structure project of upper and lower panel are designed, then has carried the finite element analysis on fitting structure used the Altair HyperWorks software, has obtained better fitting structure and selected the materials. Finally has carried size optimization and weight loss analysis on fitting structure using OptiStruct software.
