| 中文摘要: |
| 目的 研究了 2 种不同宽度规格的充气垫缓冲材料在不同跌落高度下的缓冲性能。 方法 对每种规格气垫在不同跌落高度下分别使用 5 个不同质量块进行了动态冲击试验,绘制了最大加速度-静应力曲线,研究了跌落高度对充气垫动态特性的影响,并比较了不同宽度规格充气垫动态缓冲应用特性。 结果 同一规格的充气垫随着跌落高度的增加, 最大冲击加速度逐渐增大; 在同一跌落高度下,较宽规格的充气垫的最大冲击加速度较小。 结论 在 1 ~ 2 kPa 载荷范围内,充气垫冲击加速度在80 ~ 170 g 的范围内变化,跌落高度变化及气柱宽度规格变化的缓冲性能测试评价了充气垫缓冲材料的缓冲包装应用范围。 |

| Objective To study the buffering performance of air filled cushions ( AFC) with two different chamber widths. Methods Dynamic impact tests were carried out using five different masse blocks for each type of cushions under different drop heights, and the peak acceleration-static stress curve was obtained. The influence of the drop height on the dynamic characteristics was studied, and the dynamic buffering application features of the two types of cushions were compared. Results For AFCs of the same specification, with increasing the dropping height, the peak acceleration increases gradually; at the same drop height, AFCs with greater chamber widths had smaller impact acceleration. Conclusion Under 1 ~ 2 kPa static stress, the impact acceleration of the AFCs ranges from 80 ~ 170 g. Evaluations by the dynamic impact test to the AFC samples provide guide lines to cushion packaging applications. |
