基于离散元法的水平螺旋输送机仿真模拟与分析

Simulation and Analysis of the horizontal screw conveyor Based on the Discrete Element Method

基于离散元法,应用Inventor软件建立水平螺旋输送机三维实体模型,将该模型导入EDEM软件进行仿真模拟。分析验证了水平螺旋输送机转速和填充率分别为200r/min和20%时,螺旋输送机输送一定质量物料消耗的功率最小;通过仿真模拟得出填充率为20%、50%、70%时大米颗粒平均速度变化规律以及螺旋输送机受力情况。

Based on the discrete element method, using Inventor to establish a three dimensional model of horizontal screw conveyer, to import the model into EDEM software simulation. It was gained by analyzing that when the rotational speed of the screw conveyer and the volumetric fill level was 200 rpm and 20% respectively, transporting a certain mass material consumed power was to minimize; Through simulation obtain the average speed change rule of rice grain and the force situation of screw conveyor, when the volumetric fill level is 20%, 50%, 70%.
