瓦楞纸箱高度与层数对耐压值的影响

瓦楞纸箱承受轴向力的能力主要由四个侧面瓦楞纸板的轴向承受力确定,本文将瓦楞纸箱侧面瓦楞纸板看作简支及自由边界条件下的弹性正交板,推导方程,利用加权残数法进行数值计算,画出箱体高度与层数同耐压值的关系曲线,与试验数据比较,基本相符。

Effect of the Height of Corrugated Paper Boxes and Their Layers on the Pressure-resisting Values

The side walls of the corrugated paper box are taken as the elastic orthogonal plates which are under the simple beam and free boundary conditions to develop theequations, calculate the values by means of weighted residue methods and to makethe drawings of the box height as well as the curves of the layers with the pressure-resisting values, which is found to be basically fitted to the testing data.
