Research on a Dynamic Analysis System of Paper Delivery Mechanism Model

The performance of paper delivery mechanism in a printer is crucial to the color process resolution of the whole machine. In order to ameliorate the dynamic characteristic of a high speed paper delivery system, a three- dimensional model is established and simplified. In addition, the torque fluctuation, transverse vibration as well as torsional vibration generated by AC motor are analyzed and elaborated in this paper. Further more,the electromechanical equation of a paper delivery system is set up. After careful analysis and consideration, it is concluded that several factors such as the torque fluctuation of an AC motor drive system will have significant impact on the dynamic performance of the mechanism and its relationship with drive system parameter and structural parameter. Therefore it could ameliorate and improve the dynamic characteristic of paper delivery system in a printer.
