| 目的 在不同形状的压痕条件下，对瓦楞纸箱进行抗压试验，研究纸箱的变形情况和抗压能力。方法 首先设计无压痕纸箱、一字型压痕箱、八字型压痕箱以及菱形压痕箱；其次将各种压痕形状下的纸箱，利用纸箱抗压试验机进行空箱抗压实验，记录各自的最大压溃力；最后对实验数据进行分析，明确抗压强度与压痕形状的关系。结果 不同压痕形状对瓦楞纸箱的抗压强度有不同程度的影响，其中菱形影响最大。菱形压痕通过阻碍纸箱变形趋势可提高瓦楞纸箱的抗压强度。结论 在瓦楞纸箱侧板上通过施加阻碍纸箱工字型变形的压痕（如菱形压痕），可以增加瓦楞纸箱的抗压强度，对瓦楞纸箱的生产设计具有参考意义。 |

| The work aims to carry out compression test on corrugated box to study the deformation and compressive capacity of the box under the indentation conditions of different shapes. Firstly, the non-indentation box, the cross-type indentation box, the eight-shaped indentation box and the diamond-shaped indentation box were designed. Secondly, the boxes under various indentation shapes were subject to empty container compression test by the box compression tester to record their respective maximum crush force. Finally, the experimental data were analyzed to specify the relationship between compressive strength and indentation shape. Different indentation shapes had different effects on the compressive strength of corrugated boxes with diamond ones having the greatest influence. Diamond indentation could increase the compressive strength of corrugated boxes by hindering the deformation trend of the box. The compressive strength of the corrugated box can be increased by applying a diamond indentation, which hinders the indentation subject to I-shaped deformation of the box on the side plate of the corrugated box, and has reference significance for the production design of the corrugated box. |
