摘　　要：利用万能实验机分别对钙塑瓦楞纸板、蜂窝纸板和复合结构进行静态压缩实验,得到了对应的静态应力-应变曲线,进而通过计算得到相应的能量吸收-最大应力曲线,并对其曲线进行了对比分析。最后以不同的静态压缩速度对复合结构进行静态压缩实验,得到了复合结构在不同静态压缩速度下的应力-应变曲线,建立了最大应力-静态压缩速度的理论模型,并利用最小二乘法识别模型中的参数,建立的理论模型可以直接应用于缓冲包装设计。Basing on universal testing machine,static stress-strain curve of calcium plastic corrugated paper-board,honeycomb paperboard and composite structure were obtained,respectively.Then corresponding energy absorption-stress curve of three different types of cushioning structure,namely,composite cushioning structure made from honeycomb and calcium plastic board,single-layered honeycomb and calcium plastic board were compared and analyzed subj ected to different static compression loadings,and deformation modes of composite cushioning structure were examined.Finally,the empirical formula of the maximum stress-compressive speed for the composite structure was established and corresponding parameters in the model were identified by the least squares method.The experimental results investigate that the theoretical model can provide guidance for cushioning packaging design.
