摘　　要：随着碳纤维复合材料的发展,因其比强度高、比刚度高等优点成为了无人机机翼设计的首选材料。根据大展弦比无人机机翼建立了三维模型,通过ANSYS中ACP模块校核了机翼复合材料的强度、刚度及稳定性,基于响应面优化(Response Surface Optimization)中的多目标遗传算法(MOGA),对复合材料的铺层角度、厚度、区域进行了分级优化。在150 m/s飞行速度工况下,优化后机翼最大变形由原来的20 mm变为33 mm,Tsai-Wu因子由0.53变为0.586,在符合性能要求的前提下重量下降45.4%,为无人机增加载荷能力或延长续航时间提供了方便。该优化方法为针对复合材料在航空结构的优化设计提供了参考。With the advancement of carbon fiber composite materials,it has emerged as the preferred choice in drone wings design due to their high specific strength and specific stiffness.We constructed a three-dimensional model based on a high aspect ratio drone wing and verified the strength,stiffness,and stability of the wing composite materials by using the ACP module in ANSYS.By utilizing the multi-objective genetic algorithm(MOGA)within response surface optimization,a hierarchical optimization was conducted on the layup angle,thickness,and region of the composite materials.Under a flight speed condition of 150 m/s,the optimized wing maximum deformation increased from 20 mm to 33 mm,and the Tsai-Wu factor rose from 0.53 to 0.586.It resulted in a 45.4%weight reduction while maintaining performance requirements,and facilitated the increased payload capacity or extended endurance for drones.This optimization method provided a valuable reference for the optimal design of composite materials in aviation structures.
