摘　　要：对4种不同厚度的蜂窝纸板进行了静态压缩的完全加载和二次加载实验，结果表明：完全加载过程有4个明显的阶段；最大压力都为屈服力的2～3倍；30mm厚度的蜂窝纸板其屈服阶段占厚度的百分比最大；二次加栽的实验曲线分为3个阶段，可以有效消除蜂窝纸板的屈服强度峰值，改善蜂窝纸板的缓冲特性。ANSYS软件模拟分析表明：距离面纸1／5-2／5处的蜂窝纸芯最容易屈服变形；粘结处变形比各面上变形量大；中间部位易产生向内变形，而两端易产生向外变形。Fully loaded and quadratic load static compression test were carried out on honeycomb paperboard of four different thicknesses. Results showed that there are four distinct phases during the process of fully loaded; maximum pressure is 2-3 times to yield strength; the 30 mm honeycomb paperboard has the largest yield phase percentage of the four; quadratic load curve is divided into three stages of the experiment, and the yield strength peak of the honeycomb paperboard is eliminated, which can improve the cushioning properties of honeycomb paperboard. At the same time, simulation of the compressed deformation of a single honeycomb paper- core was analyzed via ANSYS software. Results showed that location of 1/5-2/5 apart from the face paper of the honeycomb paper-core most likely to yield; bonded surfaces have larger deformation than other surface; middle location of the paper-core is easy to deform inward while at both ends deform outward easily.
