| 目的 研究整体包装件跌落时内装PET光栅包装盒的安全性，根据跌落过程中力的传递方式和受力部位进行有效缓冲防护，达到节约包装成本的目的。方法 将质量为10 kg的包装件在高度0.61 m下进行跌落冲击试验，基于试验数据获得包装盒、泡沫衬垫的冲击加速度、跌落变形量参数。结果 得到了包装盒、泡沫衬垫在跌落冲击过程中冲击力的变化规律，泡沫衬垫吸收了大量冲击，延长了冲击脉冲接触时间，减少了传递到包装盒上的冲击力。结论 包装件发生跌落时，泡沫衬垫开始被压缩、吸收外部冲击力，保护内部包装盒，在反弹阶段包装盒遭受的损害大于碰撞初期。结果显示，在泡沫衬垫和外瓦楞纸箱的缓冲保护作用下，包装盒在0.61 m的高度进行跌落是安全可靠的。 |

| To study the safety of the PET lenticular carton (hereinafter referred to as the carton) when the whole package (hereinafter referred to as the package) is dropped, effective buffer protection is carried out according to the force transmission method and the force-bearing part during the fall process, so as to save the packaging cost. A 10 kg package was subjected to a drop impact test at a drop height of 0.61 m. Based on the test data, the impact acceleration and drop deformation parameters of the carton and foam cushion were obtained. As a result, the changing law of the impact force of the carton and foam cushion during the drop impact process is obtained. The foam cushion absorbs a large amount of impact, prolongs the impact pulse contact time, and reduces the impact force transmitted to the carton. When the package is dropped, the foam cushion begins to be compressed, absorbs the external impact force, and protects the inner carton. The damage to the carton during the rebound stage is greater than that at the beginning of the collision. All these prove that under the cushioning protection of the foam cushion and the outer corrugated box, the PET lenticular carton is safe and reliable to drop at a height of 0.61 m. |
