| 中文摘要: |
| 为探究蜂窝纸板在不同程度疲劳振动下缓冲特性的变化规律,通过对多种湿度环境下处理的纸板进行不同程度的疲劳振动,再进行准静态压缩试验,并借助Matlab 软件得到其应力-应变曲线、缓冲系数与湿度、振动次数关系曲线、塑性形变及能量吸收曲线。结果表明,随着振动次数和相对湿度的不断增加,材料的承载能力、剩余屈服力、缓冲效果、吸能特性都随之减弱,且随应变大小而有所不同。振动后的蜂窝纸板与振前相比各项性能都有响应减弱,此研究可以为产品不同环境条件和物流情况下的缓冲包装设计提供理论依据。 |
| 英文摘要: |
| The cushioning properties of honeycomb paperboard under different degrees of vibration fatigue were studied. Paperboard of different vibration fatigue degrees was tested under several humidity environments. Quasi-static compression was carried out and the stress-strain curve, relationship curve of cushioning coefficient and humidity, vibration frequencies, plastic deformation, and energy absorption curve were obtained with Matlab software. The results showed that material bearing capacity, residual yield force, the cushioning effect, and energy absorbing characteristic were weakened with the increasing number of vibration and relative humidity; the strain were different. It was concluded that various properties of honeycomb paperboard are weakened by vibration fatigue. The purpose was to provide theoretical basis for design of cushioning packaging products under different environment and logistics conditions. |
