| 目的 基于低密度聚乙烯材料设计一种包装箱的缓冲结构，以满足冲击加速度的设计要求。方法 采用低密度聚乙烯材料对应的最大加速度-静应力曲线进行理论计算，设计出包装箱缓冲结构的初始模型，运用Ansys Workbench有限元仿真软件对包装箱整体进行水平跌落仿真，并对仿真结果进行分析。结果 当缓冲垫设计厚度为75 mm时，包装箱整体跌落后受到的最大冲击加速度低于40g，满足设计要求。结论 基于低密度聚乙烯材料设计的缓冲结构能够对包装箱提供有效的缓冲防护，缓冲性能满足要求。 |

| The work aims to design a cushioning structure of packaging box based on low density polyethylene to satisfy the design requirement of impact acceleration. The maximum acceleration-static stress curve of low density polyethylene was used for theoretical calculation, and an initial model of cushioning structure of the packaging box was designed. Ansys Workbench (finite element simulation software) was applied for the horizontal drop simulation of the whole packaging box and the simulation result was analyzed. When the design thickness of cushion was 75 mm, the maximal impact acceleration of the whole packaging box was below 40g after its drop, which satisfied the design requirements. The cushioning structure designed based on the low density polyethylene material can provide effective cushioning for the packaging box, and the cushioning property satisfies the requirement. |
