中文摘要:
      目的 以六边形蜂窝纸板为研究对象,研究厚度对其异面冲击性能的影响。方法 通过动态冲击实验来分析接触力、最大接触力、最大位移、最大应变、吸收能与单位厚度冲击能之间的关系,研究厚度为30,40,50和60 mm等4种蜂窝纸板的异面冲击力学性能。结果 当冲击能一定时,随着蜂窝纸板厚度的增加,接触力逐渐减小,接触时间逐渐变长;当单位厚度冲击能一定时,厚度与最大位移和吸收能成正比例关系,厚度与接触力、最大接触力、最大应变成反比例关系;对于任一厚度的蜂窝纸板,最大接触力、最大位移、最大应变、吸收能随单位厚度冲击能的增加而增加,且与其呈线性关系。结论 当冲击能相同时,不同厚度蜂窝纸板的吸收能几乎相同,可知蜂窝纸板吸收能量的能力与蜂窝纸板的厚度无关,取决于冲击能量的大小。
英文摘要:
      The work aims to explore the influence of thickness upon its out-of-plane impact properties by taking the hexagonal honeycomb paperboard as a study object. The relations among contact force, maximum contact force, maximum displacement, maximum strain, absorption energy and impact energy per unit thickness were analyzed through the dynamic impact tests. On the basis of that, the out-of-plane impact properties of four honeycomb paperboards at the thicknesses of 30, 40, 50 and 60 mm were studied. The contact force gradually decreased and the contact duration gradually increased with the increase in the honeycomb paperboard thickness for the given impact energy. When the impact energy per unit thickness was specified, the thickness was directly proportional to the maximum displacement and absorption energy; while the thickness was inversely proportional to the contact force, maximum contact force and maximum strain. For the honeycomb paperboard of any thickness, the maximum contact force, maximum displacement, maximum strain and absorption energy would linearly increase as the impact energy per unit thickness increased. For the same impact energy, the absorption energy of honeycomb paperboard of different thicknesses is almost the same. As a result, the absorption energy capacity of honeycomb paperboard, only depending upon the magnitude of impact energy, has nothing to do with its thickness.
