中文摘要:
      目的 以六边形蜂窝纸板为对象,研究内含气体对其异面冲击性能的影响。方法 通过动态冲击实验分析内含气体对接触力、最大接触力、最大位移、最大应变和吸收能的影响,得出不同孔隙率时,蜂窝纸板的接触力-时间曲线,最大接触力、最大位移、最大应变、吸收能与冲击能曲线和吸收能-孔隙率曲线。结果 在给定冲击能的情况下,最大接触力与吸收能随着孔隙率的增大而减小,最大位移及最大应变随着孔隙率的增大而增大。在孔隙率一定时,最大接触力、最大位移、最大应变和吸收能随冲击能线性增大。此外,冲击能越大,接触力达到峰值的时间越短,接触持续时间越长。结论 在动态冲击实验中,内含气体使蜂窝纸板吸收冲击能的能力明显增强,并且当冲击能一定时,孔隙率越大,蜂窝纸板越容易被压变形,吸收能越少。
英文摘要:
      The work aims to study the influence of entrapped air on its out-of-plane impact properties with the hexagonal honeycomb paperboard as the object. The influences of entrapped air on contact force, maximum contact force, maximum displacement, maximum strain and absorption energy were analyzed through the dynamic impact experiment. Meanwhile, the contact force vs. time curve, the maximum contact force, the maximum displacement, the maximum strain, the absorption energy vs. impact energy curves, respectively, and the absorption energy vs. the percentage of holes curve for honeycomb paperboard were obtained for the different percentages of holes. For the specified impact energy, the maximum contact force and absorption energy decreased and the maximum displacement and maximum strain increased as the percentage of holes increased; for the given percentage of holes, the maximum contact force, maximum displacement and maximum strain as well as the maximum absorption energy linearly increased just as the impact energy increased. In addition, the higher the impact energy, the shorter time the contact force took to reach its peak value and the longer the contact duration. In the dynamic impact experiment, the ability of absorbing impact energy of honeycomb paperboard is obviously enhanced by the entrapped air, and for the given impact energy of honeycomb paperboard, it is concluded that the honeycomb paperboard will readily tend to be compressed and deformed and the absorption energy will be less as the percentage of holes increases.
