| 中文摘要: |
| 目的 对蜂窝纸芯静态压缩性能进行分析。 方法 基于有限元软件对蜂窝芯层静态压缩性能进行仿真。结果 得到了蜂窝芯层不同位移下的变形图、 应力分布图以及后处理曲线。结论 仿真结果与试验相吻合， 芯层的破坏从上端开始， 弹塑性阶段有明显的屈服波， 屈服波数目随着边长比增大呈阶梯状上升。蜂窝芯层应力分布显示随位移增加， 载荷的承载主体从蜂窝壁板过渡到蜂窝楞， 解释了试验中粘结处易开胶现象。 |

| This study analyzed the static compression performance of honeycomb paper-core. Based on the finite element analysis software, the static compression process of honeycomb core layer was simulated. The deformation, stress distribution and other processing pictures in different displacements were obtained. The simulation results were consistent with the experiment results. Crush started at the top of the core layer. There were yield waves in the elastic-plastic stage and the number of yield waves increased in stair-step shape along with the increase of side length. Stress distribution showed that load bearing transferred from the honeycomb panel to the cellular edge along with the increase of displacement, which can explain the tackless at adhesion due to stress concentration in experiment. |
