摘　　要：建立了无人机复合材料尾翼结构的分析和优化模型,在结构初始尺寸的基础上,首先以复合材料失效因子和金属结构许用应力为约束,开展了以结构质量最小为目标,以各部件厚度为设计变量的优化设计。在尺寸优化结果的基础上,采用等效弯曲刚度法优化得到了层合板的最优铺层顺序。优化结果表明:优化后尾翼的结构质量明显降低,静力计算结果满足设计要求。The analysis and optimization model of a UAV composite tail is established in this paper. On the basis of the initial size of structure,the optimum design of the structure weight is carried out subjected to the composite failure factor and the metallic structure allowable stress with the minimum quality of structure and the thickness of each component as the design variables firstly. Based on the results of the size optimization,the optimal stacking sequence of the composite laminate is obtained by the method of equivalent bending stiffness. The optimization results indicate that weight of the composite tail decreases significantly,and the static calculation results meet the design requirements.
