摘要：Through analyzing the disadvantages of traditional linear shale shaker, the variable linear shale shaker is proposed to improve the working performance of shale shaker. The trajectory equation is deduced based on the oscillatory differential equation. Through theoretical research and Discrete Element Method (DEM) simulation, the changing rules of trajectory gradient, throwing index and throwing velocity along the screen deck are obtained, which are in good agreement with each other. The results show that the excitation position l₀<0 is conducive to solid and drilling liquid separation and solid particles conveyance. In addition, on the base of distribution of throwing index at the inlet and outlet, the proper value ranges of excitation position and direction are decided, which are -0.5 m0<-0.35 m, 35°<β₀<45°.
