摘　　要：加筋壁板具有刚度好、重量轻、强度高的优点,现代大型飞机机翼壁板均采用这种结构形式。目前,机翼上壁板设计尚没有完备的方法,在较大程度上依靠试验和经验的分析技术,主要按稳定性设计。本文对机翼上壁板强度设计进行了系统性的研究,通过在设计技术上的提升和突破,掌握了现代飞机机翼上壁板在设计、分析、试验中的关键技术。Stiffened panel has the advantages of good stiffness,light weight and high intensity,so this kind o f structure is widely used by wing panel of modem large aircraft.The upper panel of aircraft is m ainly designed by considering stability,and the design of upper panel has no s e lfcontained methods at present,so the design is depend on the test and the experiential analysis to a great extent.In the paper,the strength design of upper panel is studied system atically,and the key technologies for strength design of upper panel of modern large aircraft are obtained through promotion and breakthrough of design.
