摘　　要：针对无人机族结构设计的相关问题,提出了一种机身为通用模块、不同展长的机翼为专用模块的飞翼无人机结构设计方案。采用结构有限元方法分别对飞翼布局无人机族进行结构强度和刚度分析,使用基于PCL语言的MSC.Patran二次开发技术,实现结构优化程序的自动运行。采用二级优化方法实现通用模块和专用模块的并行运算,给出一种模块化飞翼布局无人机族的结构优化设计方法。此方法很好地发挥了模块化策略的优势,并使无人机性能损失变小。In view of the relevant problems in the structural design of UAV family,a kind of structure design scheme of UAV with flying-wing is proposed,in which the fuselage is a general module and the wings with different lengths are special modules.The structural strength and stiffness of the flying-wing UAV family are analyzed by the structural finite element method.The secondary development technology of MSC.Patran based on PCL language is used to realize the automatic operation of the structural optimization program.The parallel operation of general module and special module is realized by using two-level optimization method.This method makes good use of the advantages of the modular strategy and reduces the performance loss of the UAV.
