中文摘要:

      目的 研究纸浆模、EPE材料的单元结构与组合结构，以提高其缓冲性能。方法 通过Ansys仿真分析单元结构的静态压缩实验，对比不同材料结构单元在静载时的承载能力，在此基础上，建立产品缓冲结构单元模型，运用Ansys/LS-DYNA的Drop Test模块进行动态跌落实验，比较不同材料结构单元与缓冲性能，并通过试验验证。结果 验证了组合结构在静载和跌落冲击时的缓冲性能优于单个缓冲结构。结论 在缓冲包装中，通过优化缓冲结构单元可提高结构的缓冲能力。

英文摘要:

      It aims to improve cushion performance by studying unit structure and composite structure of pulp mold and EPE materials. Ansys software was used to simulate analysis of static compression test of unit structure and compare static load bearing capacity of structural units made from different materials. Then the result was used to establish model of buffer structural unit. Drop test module of Ansys/LS-DYNA was used to complete dynamic drop test. Different structural units and cushion performance were compared with the experimental results of drop test and validated by tests. It was concluded that the cushion performance of composite structure in case of static load and drop impact was superior to that of single cushioning structure. In conclusion, the cushion performance of buffer material structure can be improved by optimizing the cushioning structure unit in cushioning packaging.
