摘　　要：通过离散元软件EDEM,对多点进料水平螺旋给料机的输送过程进行仿真。重点考察进料点数量变化对给料机生产率、填充率以及轴向输送速度的影响。仿真结果显示,生产率、填充率随着进料点个数的增加而增大,两者变化趋势一致且存在拐点。物料轴向输送速度随着进料点个数的增加而减小,在料态饱和后又保持恒定,不受进料点个数影响。这些特点对多点进料水平螺旋输送机的设计具有一定的参考意义。Through the discrete element software EDEM,the conveying process of the multi-point feeding horizontal screw feeder is simulated.Focus on the impact of changes in the number of feeding points on feeder productivity,filling rate and axial conveying speed.The simulation results show that the productivity and filling rate increase with the increase of the number of feeding points,and the trend of the two is consistent and there is an inflection point.The axial conveying speed of materials decreases with the increase of the number of feeding points,and remains constant after the material state is saturated,regardless of the number of feeding points.These characteristics have certain reference significance for the design of multi-point feeding horizontal screw conveyor.
