| Abstract | TP391.9%O347.7; 为更好地模拟小麦籽粒(麦粒)振动筛分过程,该文在现有离散元接触模型基础上,通过EDEM软件应用程序编程接口,构建了一种麦粒黏弹塑性接触模型.该接触模型法向方向通过将Kuwabara and Kono非线性黏弹性接触模型中的黏性耗散项引入Thornton滞回接触模型进行构建;切向方向采用简化Thornton切向接触模型;滚动摩擦力矩计算同Hertz-Mindlin(no slip)接触模型.法向模型参数标定采用单轴加载-卸载试验、碰撞试验,分别构建了模拟-试验接触力误差平方和与麦粒屈服重叠量、恢复系数与法向阻尼系数的二阶回归方程,得到麦粒屈服重叠量为7.63×10-6 m,麦粒-麦粒/钢板法向阻尼系数分别为190.68和306.65.切向模型参数利用旋转鼓试验进行标定,得到最佳麦粒-麦粒/钢板静摩擦系数组合为0.40和0.44.最后利用振动筛分试验对所标定参数进行验证,模拟与试验所得筛下麦粒质量分数最大误差为8.97％,模拟中筛下物分布规律与试验结果无显著性差异,表明所建立的接触模型及标定的参数能够很好地模拟麦粒振动筛分过程.该文也可为其他农业物料黏弹塑性接触模型构建及其参数标定提供参考. |
