目的 旨在探讨抗事故包装箱在低速冲击条件下的冲击保护设计，以提高其对内部物品的保护能力，确保在跌落或碰撞事件中的安全性。方法 利用落锤冲击试验复现低速冲击环境，对3种不同缓冲层设计的冲击保护装置进行了细致的试验分析，评估并对比了它们在防护性能上的表现。结果 试验结果表明，在进行的24组试验中，采用双层组合抗冲击设计的液固耦合冲击保护装置，以其卓越的性能达到了99.50%的冲击防护效率，突显了其在防护性能上的显著优势。同时，改变落锤的下落高度以及内部填充非牛顿流体的黏度，对冲击防护效率有着重要的影响。结论 成功验证了缓冲层设计对提高抗事故包装箱抗冲击性能的重要性。通过合理设计冲击保护装置，可以有效提升包装箱的抗冲击能力，为高风险物品的安全运输提供了科学依据。

The work aims to explore the impact protection design of anti-accident packing box, to enhance their protective capacity for internal items under low speed impact conditions, ensuring safety during falling or collision. Meticulous drop-weight tests were conducted to simulate low speed impact environments, and three kinds of impact protection devices with different buffer layer designs were tested and analyzed in detail, and their protective performances were evaluated and compared. The test results showed that in 24 groups of tests, the liquid-solid coupling impact protection device with double-layer impact resistance design achieved 99.50% impact protection efficiency with its excellent performance, which highlighted its remarkable advantages in protection performance. Moreover, changing the drop height of the weight and the viscosity of the internal non-Newtonian fluid had significant effect on impact protection efficiency. The findings verify the importance of well-designed buffer layers in significantly enhancing the packing box impact resistance. By reasonably designing the impact protection device, the impact resistance of the packing box can be effectively improved, which provides a scientific basis for the safe transportation of high-risk goods.
