目的 采用改进包装的方式降低乘客安全气囊（PAB）工厂包装件的运输危险性。方法 依据乘客安全气囊在联合国外部火烧试验（UN6c试验）的结果，结合LS-DYNA动力有限元软件的分析，先后采用网格式和条栅式金属丝网笼包装控制金属迸射物的产生。结果 条栅式金属丝网笼包装成功束缚了所有动能大于8 J和动能大于20 J的金属迸射物，使乘客安全气囊工厂包装件成功通过了联合国外部火烧试验。结论 改进后的包装符合联合国关于危险货物运输的建议书（TDG）中对危险品包装的有关要求，将原分类为第1类（爆炸品）的乘客安全气囊工厂包装件降低为第9类（杂项危险品），使乘客安全气囊（PAB）工厂包装件适合更多形式的运输。

The work aims to lower the transport hazard of the PAB factory package by packaging improvement. According to the results of the UN6c test of PAB, and combined with the analysis of LS-DYNA dynamic finite element software, the packaging in the forms of mesh-like cages and strip-like cages was successively used to control the metallic projections. The metallic projections with kinetic energy exceeding 8 J and 20 J were successfully restricted by the packaging with strip-like cages, so that the PAB factory package successfully passed the UN6c test. The improved packaging meets the relevant requirements of dangerous goods' packaging in recommendations on the transport of dangerous goods (TDG). The PAB factory package originally classified into Class 1 (explosives) is reduced to Class 9 (miscellaneous dangerous goods), and can be transported in more forms.
