通过压缩试验,研究了蜂窝纸板二次加载时的缓冲性能,并与首次加载时的缓冲性能进行对比分析,表明蜂窝纸板二次加载时没有首次加载时的峰值,直接进入屈服平台,从而能更早更好地进入工作状态.同时,也对用经过预压的蜂窝纸板和没有经过预压的蜂窝纸板叠加而成的组合试样的缓冲性能进行试验研究,结果表明,预压过的试样迅速进入减振的工作状态,未预压的试样基本不变形,只对较大的冲击载荷起到缓冲作用,这有助于保持外包装箱的外观平整.
Through the compression test, the cushioning performance of honeycomb paperboard during secondary loading was studied and compared with the cushioning performance at the first loading. It shows that honeycombboard has no peak at the time of first loading and can directly enter the yielding platform As early as possible to enter the working state.At the same time, but also on the use of pre-pressed honeycomb paperboard and without prestressed honeycomb paperboard laminated composite test results showed that the pre-pressed sample Rapidly into the working state of damping, the sample is not pre-deformation of the basic deformation, only to play a larger impact load cushioning, which helps to maintain the appearance of the outer box smooth.
