摘　　要：以20°倾斜螺旋输送机为例,基于离散单元法建立了螺旋输送机离散元模型,并通过EDEM软件对螺旋输送机输送稻谷的过程进行了数值模拟.运用正交实验得出倾斜螺旋输送机输送稻谷的最佳组合为:转速200r/min、螺距176mm、填充率15%,其中影响因素大小依次为转速>螺距>填充率.On 20°inclined screw conveyor as an example,the screw conveyor discrete element model was established based on the discrete element method theory knowledge,and screw conveyor conveying process of rice are simulated through the EDEM software.Using orthogonal experimental design method,it is concluded that tilt screw conveyor conveying the best combination of rice is the speed of 200 r/min,the pitch is 176 mm,filling rate is 15%,the size of the influencing factors successively are rotational speed,pitch and filling rate.
