摘要: 为减轻复合材料无人机机翼的结构质量,利用MSC.PATRAN和MSC.NASTRAN建立大展弦比机翼结构布局优化设计的二级优化方法:第一级以机翼的刚度为目标,采用响应面法对翼梁位置进行优化;第二级以机翼结构质量为目标函数,采用遗传算法对机翼各元件的铺层参数进行优化。通过对某型大展弦比无人机机翼进行结构布局优化设计,结果表明提出的大展弦比无人机机翼二级优化方法能够在满足强度、刚度性能设计要求的前提下,减轻约25%的结构质量,减重效果明显。

Abstract: In order to reduce the weight of wing structure of composite unmanned aerial vehicle(UAV), a method of two-level optimization which uses MSC.PATRAN and MSC.NASTRAN is proposed in this paper. In the first level, a response surface method is used to optimize the location of the longitudinal wing spars. In the second level, a genetic algorithm is used to optimize the lay parameter of wing structure. As an example, a layout optimization of one type of high aspect-ratio wing structure is calculated. The result shows that about 25% weight of wing structure is reduced. It can be concluded that the two-level optimization method can significantly reduce the wing structure weight, which can satisfy the design requirements.
