为研究蜂窝纸板外包装箱对泡沫包装系统整体缓冲性能影响，基于Abaqus/Explicit程序对考虑蜂窝纸板作用的泡沫包装系统动力学行为进行有限元分析。结果表明，当冲击物初始冲击动能较小时，泡沫发挥主要缓冲作用，蜂窝纸板外包装箱对系统整体缓冲性能贡献不显著；当冲击物初始冲击动能增加到一定程度后，泡沫无法有效降低冲击物冲击速度，此时蜂窝纸板外包装箱对系统整体缓冲性能贡献显著增大。蜂窝纸板外包装箱能显著降低冲击物峰值加速度，极大改善系统整体缓冲性能。在泡沫包装系统设计时应充分考虑蜂窝纸板外包装箱作用，避免过度包装。

In order to consider the effects of honeycomb cardboard on the cushion performance of foam packaging system,the dynamic performance of foam packaging system was analysed based on the finite element code Abaqus/Explicit.The simulation results reveal that the foam layer plays a key role in buffer system under low initial impact energy,however,when the initial impact energy reaches a relative large value,the foam layer is insufficient to reduce the impact velocity and the honeycomb cardboard will assume important responsibility in the whole buffer process.The honeycomb cardboard can reduce the peak acceleration of the impact object significantly and thus improve the cushion performance of the whole system.So it is necessary to take the honeycomb cardboard effect into consideration in the process of designing cushion packaging system to avoid excessive package.
