中文摘要:
      依据蜂窝纸板初次压缩应力-应变曲线,设计了预压方案,研究了二次加载时蜂窝纸板的静态缓冲性能,并与初次加载时的缓冲性能进行了对比分析。结果表明:弹性预压对二次加载时缓冲系数曲线影响较小,塑性平台预压对缓冲系数曲线的影响较为显著;蜂窝纸板的最小缓冲系数随着预压量的增大而线性增大;弹性预压下,缓冲系数稳定时的应变随预压量的增加而增大,而塑性平台预压下,则随预压量的变大而减小;缓冲系数的波动幅度随预压量增加而逐渐减小,预压至塑性平台时,波动消失。研究为蜂窝纸板在多次冲击状况下的应用提供了理论基础。
英文摘要:
      A scheme of preloading was designed according to stress-strain curve of honeycomb paperboard under the first compression. The static cushioning performance of honeycomb paperboard under the second load was studied and compared with the performance under the first compression. The results showed that elastic preloading has less influence on cushioning coefficient curve; the effect of preloading to platform area on cushioning coefficient is significant; the minimum cushioning coefficient increases with the increase of preloading; the strain at which cushioning coefficient becomes stable increases with the elastic preloading, but decreases with preloading at platform area; the fluctuation range of cushioning coefficient decrease with preloading, and fluctuation disappears when preloading to platform area. The purpose of this research was to provide theoretic foundation for application of honeycomb paperboard under repeated impact condition.
