民机复合材料中央翼上壁板结构设计及优化

复合材料在主承力结构的应用已成为民机研制的趋势,本文对中央翼上壁板提出了复合材料结构设计方案,并通过选型试验、软件分析途径进行优化设计。同时在相同设计要求下进行了金属方案设计,得到了设计重量对比数据,为型号应用提供理论基础。

Application of composite materials in the main load-carrying structure has become the trend of commercial development, put forward in this paper, the central wing wall of composite material structure design, and through the selection test, the optimal design analysis software. At the same time, the design of metal scheme was carried out under the same design requirements, and the design weight comparison data was obtained, which provided the theoretical basis for the model application.
