摘要
通过对纸蜂窝结构特性和压缩破坏机理的分析,建立以原纸环压强度为控制的纸蜂窝结构面外载荷理论模型和临界载荷计算方法.通过理论计算与实验研究,分析结构参数对纸蜂窝面外承载能力的影响.结果表明,随着蜂窝边长、孔径比、纸壁初挠度和半波个数的增大,临界载荷均有不同程度的减小,故纸壁初变形对纸蜂窝承载能力的影响不能忽略.
The structure characteristic and collapse mechanism of paper honeycomb were analyzed. The model and calculating method for determining the out-plane load of paper honeycomb were established based on the ring crush strength of paper. Effects of the structure and material parameters on the strength were investigated by theoretical calculation and experiment. The results show that the critical load decreases in a certain extent with increasing the honeycomb length of side, hole-diameter ratio, initial deflection of paper wall and numbers of semi-wave.
