摘　　要：介绍了平底仓的发展历史、特点及平底仓系统的组成。针对目前该系统中水平螺旋输送机理论及计算机仿真研究较少的情况,应用Solid Works软件建立了合理的平底仓系统及水平螺旋输送机三维模型,将该模型导入EDEM软件进行仿真研究。通过设定模型参数和物料的运动参数,得出在不同的物料填充系数下,物料沿螺旋轴的运动矢量、水平螺旋输送机平均输送的物料颗粒数目等结果。将该结果与国外实验结果相比对,验证了利用EDEM软件进行平底仓系统水平螺旋输送机效率研究的真实性和可靠性,同时仿真使得螺旋输送机填充系数的确定更具体化,为平底仓系统的设计节省了时间,缩短了开发周期。Describes the development history flat bottom silo, characteristics and testing system, composition. For the poor current theory and computer simulation study on horizontal spiral conveyor in the system, using SolidWorks to establish a reasonable three-dimensional model of flat bottom silo horizontal screw conveyors, to import the model into EDEM software simulation. By set- ting parameters and the model material parameters, draw motion vectors of the material along the helical axis, horizontal screw conveyor average number of transported materials particles, the results with experimental results compared to abroad, flat bottom silo systems used EDEM software for the efficiency study of horizontal screw conveyors is authenticity and reliability, at the same time, the simulation makes the screw conveyor filling rate to identify more specific, save time on flat bottom bunker system design, shorten the development cycle.
