目的 对包装箱进行优化设计，并分析其在不同堆码形式下的抗压性能。方法 设计精密装甲器材包装箱的规格以及堆码形式的优化方案，并用有限元分析法分析不同堆码形式下包装箱箱体抗压性能。结果 优化设计的5种规格的包装箱在单独堆码和混合堆码形式下，其箱体的最大应力和最大变形均小于线形低密度聚乙烯材料的拉伸屈服应力。结论 优化设计的5种规格包装箱在不同堆码形式下箱体的抗压性能满足精密装甲器材包装的性能要求。

This work aims to carry out optimization design of packing box and analyze its compressive performance under different forms of stacking. Specifications of precision armored equipment packing box and optimum proposal of its stacking form were designed. Compressive performance of packing box under different stacking forms was analyzed by finite element method. Either in a separate stacking form or in mixed stacking form, the maximum stress and maximum deformation of all the 5 optimized kinds of packing box were less than the tensile yield stress of linear low density polyethylene material. In conclusion, the compressive performance of all the 5 kinds of packing box under different stacking forms can meet the packaging performance requirements of precision armored equipment.
