摘　　要：基于蜂窝纸板的结构和受力情况,对蜂窝纸板进行三点弯曲实验,分析纸蜂窝夹层结构的弯曲破坏模式和弯曲破坏过程,探究纸蜂窝夹层结构弯曲变形机理。结果表明:蜂窝纸板的弯曲破坏模式主要有面板屈曲褶皱和局部塌陷两种;蜂窝纸板的弯曲破坏过程分为5个阶段;蜂窝纸板的弯曲破坏模式与面板屈曲、蜂窝胞元壁受压形成塑性铰以及蜂窝胞元壁向中间挤压靠近有关。Three-point bending experiments were carried out on honeycomb paperboard,and its bending failure mode and process were analyzed based on the structure and force of honeycomb paperboard to investigate the bending failure mode and mechanism of paper honeycomb sandwich structure.It was found that the bending failure modes of honeycomb paperboard mainly included panel buckling and local collapse.The bending failure process of honeycomb paperboard was divided into five stages.The bending failure mode of honeycomb paperboard was related to panel buckling,plastic hinge formation and squeezing towards the center by compression of the honeycomb cell walls.
