基于跌落冲击试验，分析了双拱瓦楞纸板在冲击高度为0.3，0.4，0.6 m及相对湿度为50%，65%，90%条件下的动态冲击曲线，并建立了其能量吸收图。试验结果表明：随着相对湿度的增大，双拱瓦楞纸板的最佳能量吸收点向左下方偏移，其单位体积吸收能量的能力减弱；当双拱瓦楞纸板被完全压溃后，其最佳能量吸收点不随冲击高度的变化而改变。

Impact tests were carried out on double arch corrugated paperboard. The dynamic impact curves of the double arch corrugated paperboard in the impact height of 0.3, 0.4, 0.6 m and under the relative humidity of 50%, 65%, and 90% were analyzed. Meanwhile, the energy absorption diagrams were established. The experimental results showed that, with the increase of relative humidity, the best energy absorption points of the double arch corrugated paperboard offset to the lower left and the ability of the unit volume absorb energy decreases; when double arch corrugated paperboard fully crushing, the best energy absorption points are not changing.
