摘　　要：传统的复合材料结构设计方法未能有效利用复合材料的面内设计空间,变刚度结构的实用化为复合材料结构效能的提升提供了新的机会。使用制造工艺成本模型,以制造成本为目标函数,建立结构性能约束和制造约束,通过路径函数法和平移法对一型大展弦比机翼进行变刚度设计,建立了以制造成本为目标的变刚度复合材料结构设计优化方法,实现制造成本减少23.87%,结构减重35.58%,并分析了不同纤维路径对变刚度结构构型设计、性能、质量和制造过程的影响。Due to a number of limitations,traditional composite structure design approaches are unable to completely use the design space of composite.The realization of tow-steered composite brings new opportunities for improvement of the performance of composites.In this research,a tow-steered composite structure design optimization method is established.The optimization method was based on the manufacturing process cost model,manufacturing cost was set as the target function,performance and manufacturing constraints were established,and the fiber path function method and shifted method were selected.On a high respect ratio wing,the tow-steered design optimization realized a 23.87%deduction on manufacturing cost and a 35.58%deduction on structural weight.The research further analyzed the impacts fiber path exerts on configuration,performance,weight,and manufacturing processes.
