【摘要】 目的研究蜂窝纸板动态缓冲系数与最大静应力之间的关系。方法通过动态跌落冲击实验,研究厚度为10,20,30,40和50 mm的蜂窝纸板的动态缓冲性能。结果得到了动态跌落冲击实验的动态缓冲系数-最大静应力曲线。结论蜂窝纸板厚度越大其能够承受的冲击越大,在每个跌落高度都能找到曲线的最低点,且每种规格的蜂窝纸板都有一定的使用范围,为缓冲设计的最优化提供一定的数据参考。更多还原

【Abstract】 Objective To Study the relationship between the dynamic cushioning coefficient of honeycomb cardboard and the maximum static stress. Methods The dynamic drop impact test was used to study the dynamic cushioning properties of 10,20,30,40 and 50 mm honeycomb paperboard. Results Curve of the dynamic cushioning coefficient obtained in the dynamic drop test-the maximum static stress was achieved. Conclusion Test results showed that the larger the thickness of the honeycomb paperboard, the greater impact it could withstand. There was a lowest point in the curve at each drop height, and there was a certain usage scope for honeycomb cardboard of each specification. These results provide reference data for the optimization of buffer design.更多还原
