摘　　要：为实现螺旋输送机螺旋体的优化,以螺旋输送机关键零部件(螺旋体)的叶片形状、螺距和轴径三因素为参数变量,以仿真运行结束时螺旋输送机内部剩余颗粒数目为实验指标,利用EDEM软件进行正交仿真实验分析.结果表明:螺距对水平螺旋传送机的输送能力影响最大,其次叶片形状,轴径影响最小;叶片形状为带式,轴径为50 mm,螺距为260 mm的螺旋输送机的输送能力最好.研究结论可为提高螺旋输送机关键零部件的优化提供理论依据和参考.In order to optimize the spiral body, the blade shape, pitch and diameter of the key parts (spiral body) of the screw conveyor are taken as parameter variables, and the number of residual particles in the screw conveyor at the end of simulation operation is taken as experimental index. The orthogonal simulation experiment analysis is carried out by EDEM software. The results show that the pitch has the greatest influence on the conveying capacity of horizontal screw conveyor, followed by the shape of blade and the diameter of shaft, and the shape of blade is belt type, the diameter of shaft is 50 mm, and the conveying capacity of screw conveyor with the pitch of 260 mm is the best. The research conclusion can provide theoretical basis and reference for improving the optimization of key parts of screw conveyor.
