摘　　要：利用离散元分析软件EDEM,建立砻谷机振动喂料器和稻谷颗粒的模型,设置相应的参数,对振动喂料器中物料流进行离散元模拟。仿真出理论参数下单颗粒物料的平均运动速度大致为0.22m/s,整个物料流的平均运动速度约为0.24m/s,得出各颗粒的运动轨迹,分析其喂料均匀性。采用GM63B型测振仪,测定试验喂料器中不同振幅下物料流的运动速度,验证模拟结果的可行性,为新型振动喂料器中物料的运动分析提供参考。The models of Rubber Roller Husker Vibrating Feeder and rice particle are obtained through the discrete element analysis software EDEM.Simulate the movement of material flow in the vibrating feeder by setting up the corresponding parameters.The average speed of single particle is 0.22m/s roughly under the theoretical parameters,and the average velocity of material flow is around 0.24m/s.The trajectory is achieved and the feeding uniformity is discussed.In order to verify the feasibility of the simulation results,adopt vibration meter GM63 Bto measure the actual velocity of material flow under the different amplitude in the experimental vibrating feeder,which can provide reference for analysis of material flow in the new vibrating feeder design.
