设计了八角衬垫结构发泡聚乙烯包装系统。基于发泡聚乙烯的应力-应变数据，用有限元思想，计算了发泡聚乙烯包装系统角跌落冲击响应。得到了包装物品应力分布，为角跌落缓冲包装设计、计算提供了有效方法。

Octagon-pad structure packaging made up of expanded polyethylene was designed. Based on the stress-strain data of expanded polyethylene, the drop response of expanded polyethylene packaging system was calculated by finite element method. The stress distribution of the packaged goods was obtained. The purpose was to provide reference for angle drop cushion packaging design and calculation.
