【摘要】：目的研究异型缓冲垫的静态缓冲性能,明确其与普通缓冲垫的性能差异。方法以发泡聚苯乙烯(EPE)为试验材料,将其切割成正棱台异型缓冲垫;利用万能压力试验机分别对等效面积相同但侧面倾角不同的试样进行静态压缩试验;绘制应力-应变曲线、能量吸收曲线和缓冲系数曲线;将上述曲线与正六面体普通缓冲垫数据进行对比。结果异型缓冲垫较普通缓冲垫刚度小,且侧面倾角越小刚度越小。在相同应力水平下,异型缓冲垫与普通缓冲垫的能量吸收基本相同;在相同应变水平下,异型缓冲垫的能量吸收小于普通缓冲垫。载荷不大时,异型缓冲垫的缓冲系数小于普通缓冲垫,随着应力水平的增加,两者间的差距呈减小趋势。结论异型缓冲垫的静态缓冲性能与普通缓冲垫有明显区别,在缓冲包装设计时应根据实际情况进行充分考量,以免造成过度包装或欠包装。
[Abstract]:Objective to study the static cushioning performance of special cushioning pad and to find out the difference between it and ordinary cushioning pad. The static compression tests of samples with the same equivalent area but different side dip angle were carried out by universal pressure testing machine, and the stress-strain curves, energy absorption curves and buffer coefficient curves were drawn. By comparing the above curve with the normal cushion data of hexahedron, the results show that the stiffness of the special cushion is smaller than that of the ordinary cushion, and the smaller the side inclination is, the smaller the stiffness is. At the same stress level, The energy absorption of the special cushion is basically the same as that of the ordinary cushion, and the energy absorption of the special cushion is smaller than that of the ordinary cushion at the same strain level. When the load is small, the buffer coefficient of the special cushion is smaller than that of the ordinary cushion. With the increase of stress level, the gap between them is decreasing. Conclusion the static cushioning performance of special cushion is obviously different from that of ordinary cushion, and the design of cushioning packaging should be considered according to the actual situation. Avoid overpacking or underpacking.
