典型民用飞机外翼中央翼是通过对接肋完成对接的，对接肋的腹板在其中起到重要的传递载荷和支持结构的作用。随着制造技术的发展，先进的民用飞机上出现了整体加筋式的腹板，这有别于传统的组合式加筋的腹板结构。利用商业有限元软件Hyperworks研究在压剪复合载荷并均匀油压载荷下，这两种加强筋类型腹板在变形、局部失稳、整体失稳和破坏下的承载能力，得出了较好的加强筋形式。最后分析针对两种类型腹板的压剪复合加载试验，验证了软件的仿真分析，为关键连接区的零件设计提供方法支持。
典型民用飛機外翼中央翼是通過對接肋完成對接的，對接肋的腹闆在其中起到重要的傳遞載荷和支持結構的作用。隨著製造技術的髮展，先進的民用飛機上齣現瞭整體加觔式的腹闆，這有彆于傳統的組閤式加觔的腹闆結構。利用商業有限元軟件Hyperworks研究在壓剪複閤載荷併均勻油壓載荷下，這兩種加彊觔類型腹闆在變形、跼部失穩、整體失穩和破壞下的承載能力，得齣瞭較好的加彊觔形式。最後分析針對兩種類型腹闆的壓剪複閤加載試驗，驗證瞭軟件的倣真分析，為關鍵連接區的零件設計提供方法支持。

Outer wing connects center wing by butt joint rib, which web transfers the load from wing and provides the support for structure. With the development of manufactures, integrated rib stiffened web which is different from the traditional assembled web was employed on the advanced civil aircraft. . Based on Hyperworks ( finite element software) to uniform fuel pressure combined with compressive-shear force, two webs were compared on perform-ance under deformation, local buckling, global bucking and failure and the stiffener location were obtained. Com-pressive-shear force experiment results were analyzed, and emulation was validated. The research can support the part design in the key joint area.
