中文摘要:
      目的 瓦楞纸板由于其材料的特殊性,在运输过程中会受到环境湿度的影响,因此,首先研究标准环境下的平台应力模型,然后引入湿度因素对模型进行修正。方法 采用试验及理论建模的方法建立基于环境湿度的纵向压缩平台应力理论模型。通过实验手段探讨瓦楞原纸极限应力随环境湿度的变化规律,建立其随环境湿度的特征曲线,然后引入标准环境下的平台应力理论模型中,建立任意环境湿度下的平台应力理论模型。结果 与未考虑湿度建立的瓦楞纸板平台应力相比,考虑湿度建立的理论模型与实验结果有较好的一致性,验证了模型的准确性。结论 建立任意湿度下的理论模型对于平台应力有很好的预测作用,在实际应用中对瓦楞纸板的选择以及包装设计有很大的指导作用。
英文摘要:
      Due to the particularity of its material, corrugated cardboard will be affected by environmental humidity during transportation. Therefore, the model of plateau stress in standard environment is studied firstly, and then the humidity factor is introduced to modify the model. The method of experiment and theoretical modeling is used to establish the theoretical model of the longitudinal compression plateau stress based on the environmental humidity. Through experimental methods, the ultimate stress of corrugated paper is discussed with the environmental humidity, and its characteristic curve with environmental humidity is established. Then it is introduced into the theoretical model of plateau stress under standard environment, and the theoretical model of plateau stress under arbitrary environmental humidity is established. Compared with the corrugated cardboard plateau stress established without considering the humidity, the theoretical model established with the humidity considered has a better consistency with the tested results, which verifies the accuracy of the model. The established theoretical model under any humidity has a good predictive effect on the plateau stress, and at the same time has a great guiding effect on the selection of corrugated cardboard and packaging design.
