复合材料弹翼气动弹性剪裁设计

Aeroelastic Tailoring Design of Composite Wing

本文利用复合材料铺层结构的可设计性,采用有限元软件MSC.Patran/Nastran建立了弹翼结构的动力学有限元分析模型,在初始铺层设计下对结构进行了气动弹性分析;以弹翼结构复合材料铺层作为设计变量,颤振速度最大作为设计目标,采用多岛遗传算法进行了气动弹性优化设计。

In this paper,based on the designability of composite laminate structure,the dynamic finite element analysis model of wing structure is established by using the finite element software MSC.Patran/Nastran;the aeroelastic analysis is conducted on the structure under initial laminate design.With the composite laminate of wing structure as the design variable and maximum flutter velocity as the design objective,the aeroelastic design is optimized by using the multi-island genetic algorithm.
