中文摘要:

      目的 针对民机大型部件运输用传统木制包装箱结构重、成本高等问题，使用质量小、成本低的新型瓦楞纸材料研制民机大型部件运输用包装箱。 方法 以 APU 门为例，使用有限元软件MSC.Patran/Nastran 计算 APU 门包装箱的强度，加载侧向载荷，使用木质材料和瓦楞纸板材料进行对比。 结果 同样的结构强度，瓦楞纸箱相比木制包装箱减重 60%，瓦楞纸箱的侧向结构需要优化。结论 瓦楞纸板用作民机大型部件的包装箱材料是可行的，且有很大的质量与成本优势，但设计中应全面考虑出现的各种载荷。

英文摘要:

      Targeting at the high weight and cost of traditional wooden packaging box for civil aircraft components, new corrugated board packaging box with lower weight and cost was designed. Taking the APU door as an example, the finite element software MSC. Patran/Nastran was used to calculate the strength of APU door packaging box. The analysis of the packaging box was done by lateral load, and the comparative analysis of wood and corrugated board was carried out. It was shown that the corrugated board had 60% weight reduction as compared to wooden packaging box with the same strength, but the optimization of the packaging box should be done by lateral load. It was emphasized that corrugated board packaging box could be used for civil aircraft components, but the design load of the packaging box should be considered comprehensively. It can be used as a reference for the design of corrugated board packaging box for civil aircraft components.
