摘　　要：分别建立了典型的A、C、B楞型单瓦楞纸板的有限元模型,计算了3种瓦楞纸板的临界屈曲载荷。以临界屈曲载荷为纸板抗压能力的判定准则,定量分析了3种瓦楞纸板的抗压能力,同时研究了材料与结构对瓦楞纸板抗压能力的影响及每种瓦楞纸板的材料抗压效率。分析结果表明,大瓦楞有更好的抗压能力,其抗压能力的提高主要是依靠其结构实现的,约束条件能够极大地改变瓦楞纸板的抗压效率。The finite-element-models of the typical A-flute, B-flute and C-flute single corrugated board were established and the critical buckling loads of the corresponding finite-element-models were calculated. Taking the critical buckling load as the criteria of corrugated board compression capacity, the material compression efficiency, the structure and material contribution to each typical corrugated board on the compression strength were analyzed. The results show that the structure is the most crucial factor to improve the compression strength of the large flute corrugated board. Constraint conditions can greatly change the compression efficiency of corrugated paperboard.
