| 目的 研究瓦楞纸板楞形参数对力学性能的影响规律，以达到在保证力学性能的基础上，减少材料的使用，降低生产成本。方法 在国标规定的范围内，均匀选取了瓦楞纸板的楞宽、楞高以及楞峰半径的实验值，设计单因素实验，推导出芯纸压缩比系数公式。利用有限元方法进行准静态压缩试验，得出瓦楞纸板的边压强度以及边压强度与压缩比系数的比值。结果 压缩比系数随楞宽和楞峰半径的增加逐渐降低，随楞高的增加逐渐增高，楞宽的影响程度最大，其次是楞高，楞峰半径最小；边压强度随楞宽的增加逐渐降低，随楞高的增加整体趋势为逐渐增高，边压强度随楞峰半径的增加，其变化波动较大，在楞峰半径为1.3 mm时边压强度最大。边压强度与压缩比系数的比值在单因素变化的情况下，楞宽为3.4 mm时最大，楞高为3.75 mm时最大，楞峰半径为1.3 mm时最大。结论 瓦楞几何参数对瓦楞纸板的边压强度和压缩比系数均有明显的影响，所以选择合适的几何参数组合可以在保证强度的基础上降低材料的使用量。 |

| The work aims to reduce the use of materials and production cost on the basis of ensuring mechanical properties by studying the law of influence of corrugated parameters of corrugated board on mechanical properties. In the range of national standard, the experimental values of the width, height and radius of the corrugated board were selected uniformly. The single factor experiment was designed to deduce the compression ratio coefficient of the core paper. The finite element method was used for quasi-static compression test to obtain the edge crush resistance of corrugated board and the ratio of edge crush resistance to compression ratio coefficient. The compression ratio coefficient gradually decreased with the increase of the width of the corrugated unit and the radius of the corrugated peak, and increased with the increase of the height of the corrugated unit. The width of the corrugated unit had the largest influence, followed by the height of the corrugated unit and then the radius of the corrugated peak. The edge crush resistance gradually decreased with the increase of the width of the corrugated unit, and increased with the increase of the height of the corrugated unit. The edge crush resistance fluctuated greatly with the increase of the radius of the corrugated peak. The edge crush resistance was the largest at 1.3 mm. Under the condition of single factor variation, the ratio of edge crush resistance to compression ratio coefficient was the largest when the width of the corrugated unit was 3.4 mm, the height of the corrugated unit was 3.75 mm, and the radius of the corrugated peak was 1.3 mm. The corrugated geometric parameters have obvious influence on the edge crush resistance and compression ratio coefficient of corrugated board; therefore, choosing the appropriate combination of geometric parameters can reduce the use of materials on the basis of ensuring the edge crush resistance. |
