摘　　要：运用Solid Works设计了一种悬挂式4层摇床,根据该摇床的工作特点,结合流体力学相关理论对颗粒在床面上的运动规律进行了分析;运用FLUENT对摇床进行流体动力学分析,分析比较了摇床在不同操作参数下颗粒沿床面横向及垂直床面方向上的运动状况。结果表明,粗砂摇床选别效果随着颗粒密度的增加而增强,分离效果随着粒度的增大而增强;床面横向调坡角度选择8°、冲程、冲次分别选择22 mm、270次/min时最有利于粗砂摇床的分选,提高了摇床的选别效果。Solid Works was applied to design a kind of four-layered suspended shaking table. According to its working characteristics and in combination with the fluid mechanics theory, the motion laws of particles on the table deck were analyzed. And then, FLUENT was applied to conduct fluid mechanics analysis on the shaking table, and the motion of particles along horizontal direction and vertical direction of the deck at various operating parameters of the shaking table was analyzed and contrasted. The results showed： the separation effects of coarse sand by the shaking table enhanced with the increase of particle density and particle size; while the horizontal slope angle was selected as 8°, the stroke as 22 mm and the frequency as 270 times/min, the separation effects of coarse sand by using the shaking table was the best.
