| 中文摘要: |
| 采用四元件模型对不同楞型的瓦楞纸箱的压缩蠕变特性进行了研究。研究结果表明： 四元件模型可以用于模拟不同楞型的瓦楞纸箱的短期蠕变行为；在3种楞型中，B型瓦楞纸箱的瞬时弹性变形系数数值最小；A型瓦楞纸箱在Kelvin模型中的延时弹性变形系数和粘性系数最小；Maxwell模型中的粘滞系数与应力水平关系明显，随着应力水平的上升，下降比较明显，其中A型瓦楞纸板不可恢复永久变形最大；随着应力水平的上升，各种楞型的瓦楞纸箱的松弛时间均呈明显下降趋势，其中A型瓦楞纸箱下降程度最为明显。 |
| 英文摘要: |
| Four elements model was applied to study the creep performance of corrugated box of different flute-type. The results showed that four elements model can be used to simulate short time creep of corrugated box; the instantaneous elastic coefficient of B flute corrugated box was the smallest among the 3 flute-types; the delayed elastic coefficient and glutinous coefficient of A flute corrugated box in Kelvin model were the smallest; the glutinous coefficient in Maxwell model decreases when stress level increases, which suggests obvious relativity; the relaxation time decreases obviously when stress increases; the unrecoverable permanent deformation of A flute corrugated box is the biggest; the relaxation times of corrugated box of different flute-types decreases obviously when stress increases; the decline degree of A flute corrugated box is the most obvious. |
