中文摘要:
      目的 研究蜂窝纸板的内部气体对其静态缓冲性能的影响规律。方法 通过静态压缩实验,研究在不同孔隙率的条件下蜂窝纸板的缓冲性能。结果 通过静态压缩实验,得到了应力-应变曲线,对比不同孔隙率条件下的应力-应变曲线,可以观察到孔隙率越大,蜂窝纸板在压缩过程中的静态峰应力越小,蜂窝纸板越容易被压变形,并且形成的密实层越薄,其中孔隙率为0与孔隙率为100%时的应力-应变曲线变化明显,且气体泄漏不受厚长比和孔径尺寸的影响。结论 在静态压缩过程中,蜂窝纸板内的气体使蜂窝纸板所能承受的应力明显增强,并且通过理论推导,得出了内含气体影响下蜂窝纸板在静态压缩过程中各个阶段的应力理论公式,为其缓冲性能的研究提供了一定的理论方法。
英文摘要:
      The work aims to research the influence of entrapped air on the static cushioning performance of honeycomb paperboard. The static compression test was used to study the cushioning property of different percentages of holes of honeycomb paperboard. Curve of the stress-strain was achieved by the static compression test. With the increase of the percentages of holes, the plateau stress of honeycomb paperboard decreased and the honeycomb paperboard was easier to be deformed by pressure, and the thinner dense layer was formed by the curve of the stress-strain of different percentages of holes. When the percentages of holes was 0% and 100%, the curve of stress-strain had obvious changes, and entrapped air was not influenced by thickness to length ratio and aperture size. In conclusion, under static compression, the stress of honeycomb cardboard is significantly enhanced due to the entrapped air. The various stages of the stress theory formula are deduced under the influence of air by the static compression test. That provides a certain theoretical method for the research of its cushioning performance.
