摘要

有效表征缓冲材料的缓冲特性对于优化设计缓冲包装十分重要。采用动态缓冲系数表征材料的缓冲性能是一种非常有效方法。基于动态压缩实验和高速图像测量技术，测量了发泡聚乙烯缓冲材料冲击过程中的动态应力—应变曲线，由此得到不同应力水平情况下单位体积的动态变形能和动态缓冲系数，从而直接表征了泡沫材料的动态缓冲性能，为缓冲包装设计提供了重要的基础数据。

Abstract

It is very important to characterize the cushioning properties of cushioning material for optimizing pack design, and it is a very effective method to characterize the cushioning properties of materials by using dynamic cushioning coefficient. In this paper, we investigate experimentally the dynamic cushioning coefficient for expandable polyethylene material. Based on dynamic compression experiments, the stress-strain curve of the cushioning material was determined by using high-speed image measurement technology, resulting in the deformation energy per unit volume and dynamic cushioning coefficient of the material can be deduced. Thereby, the dynamic cushioning property of the cushioning material has been characterized directly by the dynamic cushioning coefficient, and this research result provides an important theoretical basis for the cushioning packaging design.
