摘要
为解决现阶段工人凭经验判别瓦楞纸箱是否可以继续使用时存在判断效率低、判断不准确的问题,开发出了一套瓦楞纸箱抗压强度判定系统,帮助判别瓦楞纸箱能否继续使用。本文基于对瓦楞纸箱在循环使用中抗压强度变化规律研究基础上,通过有限元仿真模拟了瓦楞纸箱实际运输工况应力状态等并进行试验验证。然后拟合出含水率、运输距离、抗压强度之间的关系式,并验证了关系式的准确性。最后,开发出瓦楞纸箱抗压强度判定系统,提高了判别准确率及判别效率。
The recycling of corrugated cartons can significantly reduce resource waste.However,the manual determination of whether cartons can continue to be used,based on workers’experience,often suffers from low efficiency and inaccuracy.To address this,a compressive strength evaluation system for corrugated cartons is developed to assist in determining their reusability.This study begins by investigating the variation in compressive strength of corrugated cartons during recycling.The stress states under actual transportation conditions are simulated using finite element analysis(FEA),with experimental validation conducted to ensure accuracy.Subsequently,the relationship among moisture content,transport distance,and compressive strength is modeled and verified.Based on this relationship,a compressive strength evaluation system is designed to determine the reusability of corrugated cartons,significantly enhancing both the accuracy and efficiency of the assessment process.
