| 目的 探究相同温湿度环境条件下，不同程度的预压缩对不同型号蜂窝纸板缓冲性能的影响。方法 利用电子材料试验机对材料进行压缩，进而通过Matlab 软件绘制出应力-应变曲线、静态缓冲系数曲线以及能量吸收曲线。结果 预压缩限制在线弹性阶段，对蜂窝纸板各项性能无明显影响；当预压缩进入弹塑性阶段，蜂窝纸板的各项性能产生较为明显的下降；当预压缩进入塑性坍塌阶段，蜂窝纸板的各项性能显著下降，甚至丧失缓冲特性。结论 随着预压缩程度的增加，蜂窝纸板静态压缩性能、静态缓冲性能及能量吸收性能都会降低。 |

| The work aims to study the effects of different levels of pre-compression on the cushioning performance of different types of honeycomb cardboards under the same temperature and humidity. The electronic material testing machine was used to compress the materials. Then, the stress-strain curve, static cushioning coefficient curve and energy absorption curve were drawn with Matlab software. The pre-compression limited the online elastic stages and it had no significant impact on all the performances of honeycomb cardboard. When the pre-compression entered the elastic-plastic stage, all the performances of honeycomb cardboard were quite obviously decreased. When the pre-compression entered the plastic collapse stage, all the performances of honeycomb cardboard were significantly decreased and even its cushioning performance was lost. With the increase in the pre-compression level, the static compression performance, static cushioning performance and energy absorption of honeycomb cardboard will be reduced accordingly. |
