| 摘 要： | 提出了一种复合材料机翼结构的形状／尺寸综合优化设计方法，对形状／尺寸综合优化问题进行解耦处理，得到了一种双层循环优化策略。采用均匀设计法给出若干样本点，使用准则优化手段进行尺寸优化设计，构造了形状设计变量与尺寸优化结果之间的二次多项式响应面模型，采用复合形法完成了基于响应面的形状优化设计。最后，对某型大展弦比飞翼结构进行了优化设计。优化算例结果表明，所提方法可行且有效，有较高的优化效率。

| Abstract: | An effective optimization method for the shape/sizing design of composite wing structures is presentedwith satisfying weight-cutting results.After decoupling,a kind of two-layer cycled optimization strategy suitablefor these integrated shape/sizing optimization is obtained.The uniform design method is used to provide samplepoints,and approximation models for shape design variables.And the results of sizing optimization are construct-ed with the quadratic response surface method (QRSM).The complex method based on QRSM is used to opti-mize the shape design variables and the criteria method is adopted to optimize the sizing design variables.Com-pared with the conventional method,the proposed algorithm is more effective and feasible for solving complexcomposite optimization problems and has good efficiency in weight cutting. |
