| 摘 要： | 飞机外翼中央翼的对接结构非常重要,承担着传递外翼载荷到中机身和中央翼的重任。基于民用客机的一种金属外翼与金属中央翼的下壁板对接结构,分析了对接形式的传力特性。比较了对接肋下缘条开槽深度、长桁端头斜削成不同角度的情况下,对接结构的应力的分布,得出一种较优的外翼、中央翼下壁板对接形式。

| Abstract: | Wing root joint is essential in transferring the load from wing to mid-fuselage and center wing. Based on the metallic wing and metallic center wing joint, the load-transferring is analyzed. The stress distribution reactions are compared with the notch depth of lower flange and cut-out of stringer end at different design details, and the optimized wing root joint structure is obtained. |

| Keywords: | Joint Lower Panel Stringer End Notch Depth |
