摘　　要：振动输送机输送物料在运动过程中受到不连续的摩擦力及碰撞力的作用,属于强非线性动力学问题.研究物料在不同振动条件下的运动状态对振动输送机的设计至关重要.以直线振动输送机上运动的物料为研究对象,基于Coulomb摩擦定律及碰撞原理,建立了物料滑动-跳跃运动模型.并利用所建模型,分析了不同振动条件下物料运动状态的变化.研究结果表明,在物料跳跃运动过程中,存在着正向滑动甚至反向滑动,滑动作用对物料的运动有一定影响.Vibratory conveyor feeding part experiences discontinuous friction and collision, which is a typical strong-nonlinear dynamic problem. It is significant to obtain the motion state under different vibration conditions to design the vibratory conveyor. Based on Coulomb＇ s law and collision regime, the sliding-hopping motion model on a linear vibratory conveyor was established. The effects on the motion of the part were analyzed in different vibration conditions upon the proposed model. It was found that there were both forward and backward sliding in the hopping motion, which influenced the motion of the part.
