摘要
综述了近年来航空航天结构轻量化设计方法,聚焦薄壁结构与连接结构两类主要承载结构轻量化设计进行总结;针对薄壁结构,分析了面向后屈曲行为的轻量化设计、虑及缺陷的鲁棒性设计以及创新轻质薄壁领域的发展动向;针对连接结构,总结了传力路径与区域应力调控两大类设计方法。此外,就轻量化结构的高精度实验方法与数字孪生模型等共性关键问题进行梳理,并展望了未来航空航天结构轻量化设计方法发展前景,为未来研究工作和装备研发提供参考。
The lightweight design methods of aerospace structures in recent years are reviewed and summarized,and the lightweight design of the thin-walled structure and connecting structure is discussed.For thin-walled structures,the development trends of lightweight design for post-buckling behavior,robust design considering imperfections,and innovative thin-walled configuration are analyzed.For connecting structures,two design methods are introduced from the load path and regional stress regulation.In addition,the common key problems such as high-precision experiment methods of lightweight structure and digital twin model are reviewed,and the development prospect of lightweight design methods for aerospace structure in the future are prospected,which could provide reference for future research work and equipment development.
