Impact Dynamic Analysis of Horizontally Vibrated Conveyor with Coulomb Friction Modeling

摘要：

　　This paper introduces dynamic impact analysis as an effective technique for studying the response of horizontal vibrated conveyor with time-varying impact excitation by the falling of the scrap.A two degree-of-freedoms impact dynamic model is formulated considering the static and dynamic coulomb friction between the scrap and chute.Then the time integration algorithm was applied in the program to solve the dynamic equations.Using the proposed method,the impact effects of ideal single scrap and multiple scraps on the dynamic response of the conveyor were analyzed.Computational results reveal numerous interesting dynamic characteristics which can be used to forecast and control the vibration of the scrap and conveyor system.
