| 目的 设计一种新型叠层结构瓦楞纸板，解决传统瓦楞纸板耐反复冲击性能较差等问题，获得缓冲及防振性能提升的包装用新型瓦楞纸板。方法 首先设计新型纸板芯纸结构;其次设定新型纸板和传统纸板参数，并手工制作试样;最后对这2种纸板分别进行动态缓冲性能试验和随机振动试验，对比分析2种纸板性能。结果 动态缓冲性能对比试验表明，在不同跌落高度下新型纸板的缓冲性能优于传统纸板;在反复冲击条件下，新型纸板的累积缓冲性能亦优于传统纸板的。随机振动试验表明，新型纸板的减振区间为63.4～200 Hz，而传统纸板在5～200 Hz内无减振现象;新型纸板在40 Hz左右的振动传递率达到峰值4.2，传统纸板的固有频率为163 Hz，新型纸板在此频率下弹性模量相对较小;新型纸板用于公路、铁路运输包装设计时应避开40 Hz的共振频率。结论 与传统纸板相比，新型纸板的动态缓冲性能及减振性能均有提升。 |

| The work aims to design a new kind of corrugated board with laminated structure, to solve the problems of poor repeated impact resistance of traditional corrugated board and obtain a new corrugated board with improved cushioning and damping performance for packaging. Firstly, the corrugating medium structure of the new corrugated board was designed. Secondly, the parameters of the new corrugated board and the traditional corrugated board were set, and the samples were made manually. Finally, the dynamic cushioning performance test and random vibration test were carried out to the two kinds of corrugated boards, and the performance of the two corrugated boards was compared and analyzed. The dynamic cushioning test showed that the cushioning performance of the new corrugated board was better than that of the traditional one under varied drop heights. Under repeated impact, the cumulative cushioning performance of the new corrugated board was also better than that of the traditional one. The random vibration test proved that the damping range of the new corrugated board was 63.4~200 Hz, while the traditional one had no damping performance in the range of 5~200 Hz. The vibration transitivity of the new corrugated board reached a peak value of 4.2 at about 40 Hz. At the natural frequency of 163 Hz of the traditional corrugated board, the elastic modulus of the new corrugated board was relatively small. The resonance frequency of 40 Hz should be avoided when the new corrugated board was used in the packaging design for highway and railway transportation. Compared with the traditional corrugated board, the dynamic cushioning performance and vibration damping performance of the proposed corrugated board are improved. |
