摘　　要：针对振动料斗料槽在设计过程中完全依靠制作经验的情况,考虑其几何设计参数料槽升角α和振动方向角β,利用达朗贝尔原理,建立了用于判断物料运动状态的振动料斗料槽的数学模型。提出了在实现最佳送料率时物料所需的运动状态,并利用所述最佳运动状态计算出振动料斗料槽的几何参数α和β的设计范围。最后,通过对某料槽设计参数可变的直线振动料斗进行实验研究,考查了料槽几何参数α和β的变化对平均送料速度的影响。结果表明,平均送料速度随着直线振动料斗料槽升角α的增大和振动方向角β的减小而变大,这为设计高效的振动料斗提供了依据。As the vibratory feeder trough entirely on experience in the design process,considering the geometric design parameters rise angle α and vibration direction angle β of trough,Darren bell principle was used to build a mathematical model of the vibratory feeder trough through to determine the state of the movement of parts. A viewwas put forward that optimal feed rate needed corresponding moving state of components,and then the best moving state was applied to calculate the design geometric parameters rise angle αand vibration direction angle β of vibratory feeder trough. Finally,the experiment of feeding speed of a vibratory feeder with variable design parameters was made to investigate the effects of vibratory feeder＇s geometric design parameters trough rise angle α and vibration direction angle β on the feeding rate,respectively. The results showthat the greater of angle α the smaller the feed rate,the greater of angle β the greater the feeding speed which provides a basis for designing efficient vibratory feeder.
