选用某B型单瓦楞纸箱,将其切割成3段,对各段分别进行抗压试验,以探讨各段对整个纸箱强度的贡献度。考虑瓦楞纸箱的材料非线性和几何非线性,采用ANSYS有限元分析软件对纸箱上段和中段以及整个纸箱进行抗压试验仿真分析,以得到纸箱各段和整个纸箱的压缩变形结果、压溃力和压溃位移。结果表明:仿真分析结果与抗压试验结果基本一致,从而验证了所建模型的可行性,且纸箱的强度基本上取决于横向皱褶。
選用某B型單瓦楞紙箱,將其切割成3段,對各段分彆進行抗壓試驗,以探討各段對整箇紙箱彊度的貢獻度。攷慮瓦楞紙箱的材料非線性和幾何非線性,採用ANSYS有限元分析軟件對紙箱上段和中段以及整箇紙箱進行抗壓試驗倣真分析,以得到紙箱各段和整箇紙箱的壓縮變形結果、壓潰力和壓潰位移。結果錶明:倣真分析結果與抗壓試驗結果基本一緻,從而驗證瞭所建模型的可行性,且紙箱的彊度基本上取決于橫嚮皺褶。

B-type single-corrugated boxes were selected as the research object. Corrugated boxes were cut into three segments and each segment was subjected to Box Compression Test(BCT)in order to determine the contribution of different parts to the strength of the overall box. Taking the corrugated boxes’material nonlinearity and geometric nonlinearity into account, the compression experiments of the upper and mid-corrugated box and the entire corrugated box were simulated by means of ANSYS finite element analysis software. Deformation results, crushing force and displacement of each section and the entire corrugated box were obtained. The results showed that the simulation results were basically in close accordance with the BCT results, the feasibility of the model was verified, and the strength of corrugated boxes essentially depending on horizontal folds.
