1、 1 蜂窝纸板的缓冲性能分析及结构设计蜂窝纸板的缓冲性能分析及结构设计 Cushioning Property Analysis and Structure Design of Honeycomb Paperboard Abstract: Honeycomb paperboard is a new kind of packaging material which is of favorable appliance foreground. The paper compares the honeycomb paperboard with other cushioning materials oft

2、en used in the cushioning packaging design according to the basic structural characters and vibration isolation principle of honeycomb paperboard, getting the vibration isolation and cushioning characters of honeycomb paperboard. By compression tests, the curves of relations between stress and strai

3、n are obtained. The results of tests show that there are four phases obviously when compressed: elastic, elastic-plastic, plastic-landslide and solid deformations. Honeycomb paperboard has the performance of vibration isolation in the phase of elastic and the performance of cushioning in the phases

4、of elastic-plastic and plastic-landslide. Besides, by changing the compression rates in the tests, this paper measures the curves of relations between stress and strain under different transmutation rates, analyzes the effect of compression transmutation rates on the cushioning property of honeycomb paperboard. Based on data from tests, the paper establishes constitutive relationship dynamic model of honeycomb paperboard, identifies the parameters of this model. The parameters show that the mod
