摘要
目的对立式瓦楞复合纸板的静态压缩过程进行试验研究和有限元分析,研究不同楞型立式瓦楞复合纸板的力学性能。方法制作A楞、AB楞、B楞等3种不同立式瓦楞复合纸板试样,进行静态压缩实验,得到其压缩应力-应变曲线;建立3种楞型的立式瓦楞复合纸板有限元模型,进行静力学分析,得到其压缩应力-应变曲线,并与实验结果进行对比分析。结果试验和有限元分析均显示立式瓦楞复合纸板的静态压缩过程与蜂窝纸板的静态压缩过程类似,包括弹性阶段、屈服阶段、平台阶段、密实化阶段,试验和有限元分析所得到的压缩应力-应变曲线相吻合。纸板的峰值应力和平台应力与楞型有关,且随着楞高的增大而减小。结论通过试验研究和有限元分析方法得到了不同楞型立式瓦楞复合纸板的静态压缩性能,对该新型材料的应用有重要参考价值。
The work aims to conduct experimental investigation and finite element analysis on the static compression process of the vertical corrugated composite paperboard, and study the mechanical properties of different flute cal corrugated composite paperboards. Three different vertical corrugated composite paperboards of A flute, AB flute andB flute were fabricated, and the compressive stress-strain curves were obtained after the static compression test. The finite element models of three vertical corrugated composite paperboards were established and the compressive stressstrain curves were obtained after statics analysis. The two kinds of curves were compared with the experimental results and analyzed. Both experiment and finite element analysis showed that the static compression process of vertical corrugated composite paperboard was similar to that of the honeycomb paperboard, including elastic stage, yield stage, platform stage and densification stage. The compressive stress-strain curves obtained from the experiment and finite element analysis fit well. The peak stress and the platform stress of the paperboard were related to flutes and decreased with the increase of the flute height. Static compression properties of different flute vertical corrugated composite paperboards are obtained in the methods of experimental investigation and finite element analysis. They have important reference value for the application of this new material.
