| 中文摘要: |
| 以瓦楞楞型不同的B型和C型瓦楞纸板为研究对象,在7种压缩速率下进行了准静态压缩实验,分析了瓦楞纸板的变形模式和静态性能,得到了瓦楞纸板横向压缩力学性能和能量吸收性能,并绘制了不同压缩速率下瓦楞纸板的能量吸收图、能量吸收效率曲线及质量比吸能曲线。实验结果表明,低压缩速率对瓦楞纸板的最佳能量吸收点、能量吸收效率、质量比吸能等性能基本无影响；而截面几何尺寸对瓦楞纸板的能量吸收性能影响较大,在相同压缩速率下,B型瓦楞纸板的单位体积吸收能、结构变形利用率、质量比吸能均优于C型瓦楞纸板。 |
| Abstract: |
| Taking the B-flute and C-flute corrugated paperboard as research objects, the corrugated paperboards were conducted quasi-static compressive tests under 7 different compressing rates to examine deformation modes and static properties. Transverse compression mechanical characteristics and energy absorption properties were analyzed, energy absorption diagrams, energy absorption efficiency curves and specific energy absorption (SEA) curves were drawn. The results showed that, there was neglected effect of low strain rates on optimum stress of energy absorption, energy absorption efficiency and specific energy absorption of corrugated paperboard, while section geometry of the panel affected the energy absorption properties of corrugated paperboards more obviously. At the same compression rate, energy absorbed per unit volume, structural deformation utilization rate and specific energy absorption of B-flute corrugated paperboard were all greater than that of C-flute panel. |
