摘　　要：提出了一个研究发泡聚乙烯缓冲曲线的方法。该方法使用压力-能量曲线来研究缓冲包装用发泡聚乙烯的动态缓冲性能。由于获得动态缓冲曲线需要大量的冲击实验和有效的数据,该方法是获得同种材料在多种厚度、多种跌落高度条件下的动态缓冲曲线的简便方法。该方法能够提供充足的数据,并为缓冲包装设计提供最大加速度、静应力和缓冲系数的参考。The authors put forward a method to study the shock cushioning curve of EPE.The stress-energy curve was used to study the dynamic cushioning characteristics of EPE.Large quantities of shock tests and effective data are necessary for getting dynamic shock cushioning curve,so this method is a shortcut for acquiring dynamic shock cushioning curves of various thicknesses and drop heights for the same kind of material.It can provide plenteous data,and provide reference for design of cushioning package with maximum acceleration,static stress and cushion coefficient.
