中文摘要:

      目的 研究瓦楞纸箱抗压强度变化规律，提高瓦楞纸箱循环使用效率，减少资源浪费。方法 通过有限元仿真模拟不同湿度下瓦楞纸箱抗压强度以及振动时瓦楞纸箱应力情况。通过试验的方法测试模拟循环后瓦楞纸箱抗压强度变化，找出变化规律。结果 有限元分析结果得出，湿度越大，瓦楞纸箱抗压强度越低，振动时受到的应力越大;试验得出振动时间相同时，湿度越大抗压强度越低，抗压强度降低得越多。结论 通过有限元和试验的方法得出抗压强度相关公式指导判断瓦楞纸箱能否继续循环使用，可以有效提高瓦楞纸箱循环使用效率。

英文摘要:

      The work aims to study the changes in the compressive strength of corrugated cartons, improve the efficiency of corrugated carton recycling, and reduce the waste of resources. Through finite element simulation, the compressive strength of corrugated cartons at different humidity levels and the stress on corrugated cartons during vibration were simulated. The compressive strength of corrugated cartons was tested by means of experiments to summarize the law of change in compressive strength. The finite element analysis showed that the higher the humidity, the lower the compressive strength of the corrugated carton and the greater the stress during vibration. The test showed that the higher the humidity, the lower the compressive strength and the greater the reduction in compressive strength when the vibration time was the same. The compressive strength related formulae derived from finite element and test methods are used to judge whether corrugated cartons can continue to be recycled or not, which can effectively improve the recycling efficiency of corrugated cartons.
