| 摘要: |
| 对蜂窝纸芯的环压强度进行了理论分析和试验测试，得到了基准临界应力。通过对多种规格的试样进行静态压缩试验，得出了蜂窝纸板压缩性能曲线。进一步分析了临界应力随厚度、面纸、蜂窝边长变化而变化的规律，构建了以芯纸环压强度为基础的临界应力模型，利用该模型可以预测蜂窝纸板的临界应力。 |

| Abstract: |
| The ring crush strength of honeycomb paperboard was tested and analyzed theoretically, and then the base critical stress was obtained. By experiments on different samples, the static compression performance curves of honeycomb paperboard were obtained. Critical stress model was set up, which reveals the relationship of critical stress with thickness, panel, and side length. The critical stress of honeycomb paperboard can be predicted by using the model. |
| Key words: honeycomb paperboard ring crush strength critical stress model |
