DOI: 10.11817/j.issn.1672-7207.2020.10.002 . COETZEE[19]对颗粒的宏观属性和DEM微观属性进行了区分(如图3所示),同时对粒径小于40 mm的无黏性颗粒各项参数的2种校准方法(试验校准和数值校准)进行了阐述.可视化过程中特征标记主要包括:根据速度,粒径对颗粒,颗粒所在筛面区域[22]颜色进行标记;以箭头形式对颗粒运动方向上的速度矢量进行标记[18]. 图3 颗粒属性分类 Fig. 3 Particle property classification 筛分过程的稳态判定条件通常为流入和流出筛机的颗粒数量或质量达到平衡状态,或系统内的颗粒数量,质量,动能等动态信息达到稳定状态.Yade代码在仿真流程上有所区别,颗粒分批加入,逐步达到稳定,最后"释放"筛孔进行仿真.通过筛分系统内的非平衡力是否收敛于0判断筛分系统是否达到"准静态"[15......
