摘　　要：目前无人机机翼大规模采用复合材料,因为性能优越的复合材料具有很好的可设计性,所以对于复合材料机翼的研究十分重要。基于ANSYS和MATLAB联合调用技术提出了一种固定翼无人机机翼结构/材料一体化设计的优化方法:将翼梁位置的结构参数和机翼各元件材料的铺层参数作为设计变量,机翼结构质量为目标函数,采用遗传算法对机翼进行优化。通过对某型固定翼无人机机翼进行优化设计,结果表明一体化设计优化方法能够在满足强度、刚度性能的约束下,最大程度地减轻结构质量。Composites are widely used inUAV wings at present. Because composites with superior performance have good designability,it is very important to study composite wings.Based on ANSYS and MATLAB joint call technology,an optimization method of wing structure/material integration design of fixed wing UAV is proposed. The structural parameters of wing beam position and the laying-on parameters of each component of wing are taken as design variables,and the structural quality of wing is taken as objective function.Genetic algorithm is adopted to optimize the wing. Through the optimization design of a fixed wing UAV,the results show that the integrated design optimization method can reduce the structure quality under the premise of meeting the design requirements of strength and stiffness.
