摘　　要：飞机外翼与中央翼的对接结构承担着传递外翼载荷到中机身和中央翼的重任。本文首先梳理了先进民用客机的下壁板对接形式,然后给出了不同下壁板对接结构的设计要点,最后分析了典型机型下壁板对接结构的传力特性,指出下壁板结构的材料类型会影响对接结构的设计。The wing root joint of civil aircraft wing and center wing is essential in transferring the load from the wing to the mid-fuselage and the center wing. In this study,different forms of the lower panels’joints of civil aircraft wing and center wing are summarized. The key points of the design of lower panels’joints are given. Lastly,the load transferring characteristics of typical civil aircraft are analyzed,and it is shown that the material type of lower wing panels will affect the design of joints.
