摘　　要：以立式砂辊碾米机为例,运用离散元法分析软件EDEM对碾白室内物料运动过程进行仿真计算。建立碾白室和糙米籽粒的离散模型,设置相应的参数,对砂辊碾米机碾白室内物料流进行离散元模拟。得出碾白过程中糙米籽粒运动轨迹曲线、受力大小,将这些数据以图表形式显示便于分析仿真结果,研究成果为研究碎米产生机理提供了参考依据。Taking the vertical sand-roller rice milling machine as an example,this paper carries out the simulation calculation of the materials＇ movements inside the whitening chamber based on the discrete element method via the analysis software EDEM.The study sets up the discrete model of the whitening chamber and the brown rice with corresponding parameters and performs the discrete element simulation on material flows inside the whitening chamber;for the convenience of the analysis,the data of the motion locus curve and the force on the brown rice during the whitening process are presented with charts.These simulation results would provide references for the study of the generating mechanism of broken rice.
