复合材料机身加筋壁板选型研究

Study about Choice of Stiffened Structure Configuration of Laminated Composite Fuselage

针对复合材料机身加筋壁板构型选择问题,通过初步选型、优化分析以及试验验证3种形式的结合研究,对复合材料机身加筋壁板提出了两点设计建议:(1)相同质量下,帽型长桁壁板的承载能力大于T型长桁的承载能力;(2)相同质量下,相同的帽型长桁加筋板,长桁间距200 mm的壁板承载能力大于长桁间距250 mm的壁板。

Select configurations reinforced composite fuselage panels for the problem, through the preliminary selec- tion, optimization analysis and experimental verification three forms of binding studies of reinforced composite fuselage pan- els made two design proposals. 1. Under the same weight, carrying capacity hat stringer panels larger than T - stringers carrying capacity; 2. Under the same weight, the same hat truss stiffened plate, stringer spacing panels carrying capacity greater than 200 mm long girder spacing 250 mm siding.
