摘　　要：为了降低飞机机翼结构的位移变化幅度,合理优化飞机机翼结构,开展基于遗传算法的飞机机翼结构拓扑优化设计方法研究,通过飞机机翼编码矩阵、检查拓扑结构外形、设计飞机机翼拓扑结构标准化约束条件、转换飞机机翼结构适应值,完成优化设计。通过对比实验证明,设计方法在应用到实际飞机机翼结构优化中时,能够实现对其结构的合理设计,提高机翼的承载能力,进一步实现对结构总重的降低,为飞机飞行安全提供保障。In order to reduce the displacement variation range of aircraft wing structure and reasonably optimize aircraft wing structure,the topology optimization design method of aircraft wing structure based on genetic algorithm is studied.The optimization design is completed by aircraft wing coding matrix,checking the topology shape,designing the standardized constraints of aircraft wing topology structure,and converting the fitness value of aircraft wing structure.Through comparative experiments,it is proved that when the design method is applied to the structural optimization of actual aircraft wing,it can realize the reasonable design of its structure,improve the bearing capacity of the wing,further reduce the total weight of the structure,and provide guarantee for aircraft flight safety.
