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.
