目的 优化戴尔笔记本电脑Vostro 1440的缓冲包装结构。方法 了解产品特性和流通环境， 确定缓冲包装材料， 提出3个缓冲包装结构改进方案并与原方案进行对比分析， 利用Ansys软件对最佳设计缓冲结构和原始缓冲结构进行跌落仿真测试分析。结果 采用密度为0.029 g/cm3的EPE为缓冲材料， 3个改进方案都不同程度节约了材料的用量并通过了挠度校核， 其中方案3用量较少且具有多功能化， 在跌落仿真中缓冲效果优于原始缓冲结构。结论 产品缓冲包装结构将朝着绿色环保、 高效能、低成本、 多功能化趋势发展。

The paper was aimed to optimize the cushion packaging structure for Dell notebook Vostro 1440. Based on the product characteristics and circulation environment, the cushion packaging material was determined, and three sets of cushion packaging structure improvement schemes were designed and comparatively analyzed with the original scheme. The cushion packages with the optimal design and the original design were tested with drop simulation security analysis via Ansys software. Using EPE with a density of 0.029 g/cm3 as the cushion material, all three sets of improvement schemes saved material consumption to different degrees and passed the deflection check. Scheme 3 has the least material consumption and was multifunctional, besides, it showed better cushioning effect than the original cushion structure in the dropping simulation. In conclusion, product cushion packaging structure has a development trend towards environmental friendliness, high efficiency, low cost, and multi-function.
