摘要
使用粒子运动轨迹追踪实验和离散元仿真方法,探究不同含水率香菇菌渣粒子在致密化过程中拱效应的影响。通过分析8%、10%、12%、14%这4组含水率香菇菌渣粒子在压缩的4个不同阶段的运动轨迹,揭示粒子在压缩过程中受到的拱效应影响的大小。研究表明:在香菇菌渣粒子含水率为12%时,粒子运动过程中的偏转和位移最大,受到拱效应的影响最大;在香菇菌渣粒子含水率为8%时,粒子运动过程中的偏转和位移最小,受到拱效应影响最小。
The present study investigates the influence of the densification process of shiitake residue particles with different moisture contents on the arch effect.This investigation is achieved by using two methods:firstly,particle motion trajectory tracking experiments and secondly,discrete element simulation methods.By analyzing the movement trajectories of the four groups of shiitake residue particles with moisture contents of 8%,10%,12%,and 14%at four different stages of compression,the extent to which the particles are affected by the arching effect during the compression process is revealed.Research findings indicate that when the moisture content of the shiitake residue particles is 12%,deflection and displacement during particle movement reach their zenith,and are most influenced by the arch effect.It has been established that when the moisture content of the shiitake residue particles is 8%,the deflection and displacement during the particle movement are minimal,and the influence of the arch effect is negligible.
