物流包装用瓦楞纸的抗压强度数值模拟研究

Numerical Simulation of Compressive Strength of Corrugated Paper for Logistics Packaging

为了分析物流包装用瓦楞纸抗压强度的影响因素,提出了物流包装用瓦楞纸的抗压强度数值模拟研究。在理论分析的基础上,结合实验测试,计算了三种楞型瓦楞纸箱的抗压强度,将周长、高度和长宽比作为结构参数,以温湿度作为环境参数,以E楞瓦楞纸箱、B楞瓦楞纸箱和BC楞瓦楞纸箱等三种瓦楞纸箱为研究对象,测试了抗压强度。结果表明,纸箱的周长与瓦楞纸箱的抗压强度直线呈现出正相关关系,瓦楞纸箱的高度在195mm以内时,纸箱的高度对瓦楞纸箱的抗压强度影响不大,而瓦楞纸箱的抗压强度受到长宽比因素的影响比较大,但不具备规律性;在温湿度方面,温度相同时,随着相对湿度的升高,瓦楞纸箱的抗压强度越来越小,相对湿度相同时,随着温度的升高,瓦楞纸箱的抗压强度越来越大。

In order to analyze the factors affecting the compressive strength of corrugated paper for logistics packaging,a numerical simulation study on the compressive strength of corrugated paper for logistics packaging was proposed.On the basis of theoretical analysis and experimental test,the compressive strength of three kinds of corrugated boxes was calculated.The compressive strength was tested by taking perimeter,height and aspect ratio as structural parameters,temperature and humidity as environmental parameters,and E corrugated box,B corrugated box and BC corrugated box as research objects.The results show that there is a positive correlation between the circumference of the carton and the compressive strength of the corrugated carton.When the height of the corrugated carton is less than 195 mm,the height of the carton has little effect on the compressive strength of the corrugated carton,but the compressive strength of the corrugated carton is greatly affected by the aspect ratio,but it does not have regularity.In terms of temperature and humidity,when the temperature is the same,the compressive strength of corrugated boxes becomes smaller and smaller with the increase of relative humidity.When the relative humidity is the same,the compressive strength of corrugated boxes becomes larger and larger with the increase of temperature.
