| 目的 研究外包装瓦楞纸箱对整体缓冲性能的影响。方法 实验设定400， 600， 750 mm等3个等效跌落高度， 设置单种EPE与EPE/瓦楞纸板组合材料的对比实验组， 测定试样的动态压缩残余应变、最大加速度变化率， 并绘制应力-应变曲线、 最大加速度-静应力曲线及缓冲系数-最大应力曲线。结果 EPE/瓦楞纸板的缓冲性能明显优于单种 EPE， 最大加速度值平均减小 5%~13%， 缓冲系数减小2%~10%， 同时极值点的承载能力提高了20%左右。结论 瓦楞纸板组合材料的缓冲性能明显增强，考虑外包装箱瓦楞纸板的缓冲作用具有实际应用意义。 |

| To analyze the influence of outer corrugated paperboard on the overall cushioning properties. Comparative tests were designed for EPE and EPE/corrugated paperboard under three equivalent heights of 400, 600, 750 mm, and the dynamic compressive residual strain and change rate of maximum acceleration were measured. And then the stress-strain curves, maximum acceleration-static stress curves and cushion coefficient-maximum static stress curves were drawn. The cushioning performance of EPE/corrugated paperboard was better than that of EPE alone; the maximum acceleration value of EPE/corrugated paperboard averagely decreased by about 5%～13% of that of EPE alone; the cushion coefficient was decreased by 2%～10%; and the optimal bearing capacity of extreme point for EPE/corrugated paperboard was increased by 20%. The cushioning performance of EPE/corrugated paperboard was significantly strengthened. It is critical to consider the positive effect of corrugated paperboard in outer package. |
