Buckling analysis and experiment of open cylindrical thin shells under axial load

  • 摘要: 开口圆柱薄壳结构的轴向承载能力和稳定性分析是空间薄壁管式伸展机构(STEM,Storable Tubular Extendable Member)设计的关键问题之一.基于特征值屈曲分析方法,研究了轴压铍青铜开口圆柱薄壳结构在两端固支条件下的屈曲载荷与设计参数间的关系,利用幂函数拟合的方法建立了一种轴压开口圆柱薄壳屈曲载荷模型.通过铍青铜开口圆柱薄壳轴向压缩试验对特征值屈曲分析和所建立的轴压开口圆柱薄壳屈曲载荷模型进行了验证.结果表明:特征值屈曲分析方法可用于各向同性材料开口圆柱薄壳结构在两端固支条件下的轴向承载能力与稳定性分析;使用轴压开口圆柱薄壳屈曲载荷模型计算各向同性材料的开口圆柱薄壳在两端固支条件下受轴压作用时的屈曲载荷,最大误差为21%.
