非均布载荷下瓦楞纸箱的承载性能 总被引:2,自引:2,他引:0
目的研究非均布载荷下瓦楞纸箱变形与抗压强度的变化规律。方法对2种不同类型的纸箱进行局部抗压试验。首先对纸箱的不同箱面位置进行局部抗压试验,然后对纸箱的同一箱面位置进行变加载面积的抗压试验,最后分析试验数据。结果在确定加载面积的情况下,纸箱中心位置抗压强度最差,周边位置抗压强度最高;对于长方形纸箱面,其短边位置的抗压强度大于长边位置的抗压强度。在确定纸箱加载位置的情况下,加载面积越大,纸箱抗压强度越大;随着加载面积的增大,纸箱的抗压强度呈指数型增加。结论非均布载荷对纸箱抗压强度影响较大。当纸箱箱面中部承受非均布载荷时,纸箱垂直方向上会产生较大的变形,因此在瓦楞纸箱的转运过程中应尽量避免承受因局部或交错堆码产生的非均布载荷。 相似文献

A new method to enhance the compressive strength of corrugated cartons is proposed in this study. The work aims to carry out compression tests on the corrugated carton to analyze the deformation and compressive capacity of the carton under the indentation condition of different shapes. First, compression tests are carried out on nonindentation cartons, one-line indentation cartons, unclosed rhombus indentation cartons, rhombus indentation cartons, and cross-indentation cartons to record their maximum compressive force. Second, by comparing the deformation of different cartons, it is found that rhombus indentation and cross-indentation have the greatest influence on the compressive strength of cartons. Rhombus indentation will enhance the compressive strength of the carton, while cross-indentation will reduce it. Third, ANSYS Workbench is used to analyze the buckling of cartons, and the maximum compressive force of nonindentation cartons and rhombus indentation cartons is obtained. Finally, through the comparison of the finite element method and experiments, it is concluded that rhombus indentation can improve the compressive strength of cartons, which is of great significance to the industrial production of cartons. 相似文献

This study demonstrates how a human‐hand opening process for a perforated folding carton can be mapped into a path for testing. A field observation was conducted to visually record opening patterns by an observation group. The most representative opening pattern was then repeated by another observation group in the laboratory, and the resulting opening pattern and movements were captured and mapped mathematically via Matlab. The opening speeds were calculated based on opening path that is used to compare the testing machine. A fixture attempting to mirror the opening path was developed for perforated folding cartons to be tested by using tensile testing machine. The study suggested that the process, involving the identifying opening pattern, guided test and fixture equipped testing, can be applied to replication of human‐packaging interaction.
