摘要:

目的建立普通型七层瓦楞纸板和X-PLY 型瓦楞纸板的边压强度和侧压强度的回归计算方程。方法通过分析X-PLY 型瓦楞纸板的结构特征，并进行边压强度和侧压强度的对比试验。基于应力-应变曲线实验数据，讨论BBB，BAB，BCA，X-PLY（BBB），X-PLY（BAB），X-PLY（BCA）型组合板材的强度特性和承压规律，并利用SPSS软件对试验结果进行回归分析。结果因为结构的特殊性，X-PLY 型瓦楞纸板两方向的压缩强度同普通七层瓦楞纸板相比差异性较小，得到普通型七层瓦楞纸板和X-PLY 型瓦楞纸板的边压强度和侧压强度的回归计算方程误差在5%以内，模型的拟合性能较优。结论该方程可以为X-PLY 型瓦楞纸板强度的预测和纸板的配纸提供参考依据。

Abstract:

The work aims to establish a regression equation for calculation of edge compressive strength and lateral compressive strength of ordinary seven-layer corrugated board and X-PLY corrugated board. Firstly, the structural characteristics of X-PLY corrugated board were analyzed, and the comparative tests of edgecompressive strength and lateral compressive strength were carried out. Secondly, based onthe experimental data of stress-strain curve, the strength characteristics and pressure law of BBB, BAB, BCA, X-PLY (BBB), X-PLY (BAB) and X-PLY (BCA) corrugated paperboardwerediscussed. Lastly, Regression analysis of test results was carried out with SPSS software. Because of the special structure, the X-PLY corrugated board hada small difference in the compressive strength between the two directionscompared withthe ordinary seven-layer corrugated board. The regression equation for the calculation of the edgewise compressive strength and lateral compressive strength of the ordinary seven-layer corrugated board and X-PLY corrugated board was within 5%. The model has better fitting performance. This equation can provide a reference for the prediction of the strength of X-PLY corrugated board and the paper forcorrugated board.
