摘　　要：轻量化设计是运载火箭箭体结构设计的重要内容。采用理论推导的方法证明了在金属半硬壳箭体结构设计中,传统设计理论过于保守。提出一种基于有限元方法的半硬壳结构框一桁匹配性设计方法,并用该方法指导了一种大直径箭体结构设计,试验结果证明了该方法正确可行,极大减轻了结构重量。Weight is a key concern about the structure design of the launch vehicle. In this paper, theoretical analysis is employed to prove that traditional design theory for semigfid launch vehicle cylindrical structure is conservative. A matching design method of frame-stringer is drawn and is used to instruct the design of a large size metal structure. The test result shows that the method is effective which reduces the weight sharply.

关 键 词：结构 匹配性设计 减重
