目的 研究在不同疲劳损伤条件下，蜂窝纸板平台应力的变化规律和损伤机理。方法 首先将蜂窝纸板进行温湿度预处理，然后对其进行5种预压缩后再进行不同次数的疲劳压缩，接着进行准静态压缩，最后得到不同疲劳损伤条件下蜂窝纸板的本构关系曲线。结果 蜂窝纸板疲劳损伤因原纸纤维无规则排序刚度下降而引起，疲劳损伤对蜂窝纸板平台应力影响较大，在不同疲劳损伤条件下，疲劳损伤对蜂窝纸板平台应力的影响有一定的规律。结论 蜂窝纸板在运输过程中受到疲劳损伤后，必须考虑其平台应力的变化。

The work aims to study the plateau stress variation of honeycomb paperboard and fatigue damage mechanism under different conditions. First, honeycomb paperboard was subject to temperature and humidity pretreatment. Then, 5 precompression and different times of fatigue compression were carried out, followed by the quasi-static compression. Finally, the constitutive relation curves of honeycomb paperboard were obtained under different fatigue damage conditions. The fatigue damage of the honeycomb paperboard was caused by the reduction of the irregularly arranged stiffness of the paper fibers. Fatigue damage had great influence on the plateau stress of honeycomb paperboard. Under different fatigue damage conditions, fatigue damage had certain laws regarding the plateau stress of honeycomb paperboard. After the fatigue damage of honeycomb paperboard during transportation, the change of its plateau stress must be considered.
