摘　　要：借鉴蜂窝纸板平压试验缓冲系数C的计算公式,推导出其在弯曲时的缓冲参数C1,并在试验的基础上,研究了跨度对蜂窝纸板弯曲缓冲性能的影响.结果表明,在弹性阶段,大跨度的蜂窝纸板弯曲缓冲性能较好,进入屈服平台后,小跨度的试样缓冲性能较好.Refer to the formulae of compression cushioning coefficient C for honeycomb paperboard, we educed the cushioning coefficient C1 of bending. Based on experiments, we study the influence of span to flectional cushioning behavior of the honeycomb paperboards. The result show that, the cushioning properties of longer span honeycomb paperboard are better than the shorter while it is in elastic deformation. When it is in plastic deformation, the shorter is better.
