摘　　要：研究轴压桁式半硬壳结构优化设计问题。为考虑蒙皮曲板的失稳承载能力,在总体失稳下极限承载轴压叠加公式中引入附贴蒙皮宽度计算式,针对铝合金和复合材料桁式半硬壳结构,分别引入桁条剖面压应力和蒙皮附贴宽度设计变量,建立轴向压力作用下桁式半硬壳结构优化设计模型,并采用Ansys 10.0软件进行优化计算。对铝合金和复合材料桁式半硬壳结构算例进行优化设计,得到若干有实用价值的结论。The design optimization for the joist-stiffened semirigid column shell under axial loading was presented.Collateral skin width was calculated and considered in the accumulation formulas for lower-limit axial loading of general buckling.The axial stress of the joist section and collateral skin width were used as design variables for aluminum alloy and composite material structures.Structural design optimization model was established and solved using Ansys,several conclusions were obtained through calculation...
