七层瓦楞纸箱结构优化研究

目的增加七层瓦楞纸箱在堆码过程中的强度。方法对市面上常见的瓦楞组合通过Ansys进行静态仿真实验分析,并用Excel对数据进行处理,比较瓦楞组合的强度大小。在选择BBE瓦楞组合的基础上,对主要受力楞边提出了3种加筋方式来增加瓦楞纸板的强度,对3种加筋和未加筋方式进行了理论和实验的屈曲分析,比较结果,观察扩展模态。结果将数据以表格的形式显示,可以看出在相同条件下,理论和实验表明不同的加筋方式临界压力也不同。结论适当加筋能够增加瓦楞的强度,并且外加筋方式的强度最大。

Structure Optimization of Seven Corrugated Boxes

Objective To increase the strength of seven corrugated boxes in the stacking process. Methods Firstly, static analysis of the common corrugated combinations in the market was carried out by Ansys simulation, and excel was used for data processing. The strength of the corrugated combinations was compared. On the basis of choosing the BBE corrugated combination, the author proposed three ways to increase the strength of reinforced corrugated cardboard against the main force flute edge. Theoretical and experimental buckling analysis was performed for the 3 reinforced cardboard and the unreinforced cardboard, the results were compared, and the expansion mode was observed. Results The data was displayed in tabular form, it could be found under the same conditions, the theoretical and experimental results showed that the critical pressure was different in different reinforcing ways. Conclusion Appropriate stiffener could increase the strength of corrugated boxes, and the strength of the external reinforcement was the highest.
