中文摘要:
      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。
英文摘要:
      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.
