The paper aims at attacking and noise problems of high spot open-closed gripper mechanism in printing machine in a high speed situation. The analytical method of dynamic performance is presented based on the relative motion, the absolute motion, and the mechanical model. And the analytical equations are established. Then, the dynamic performance of a practical mechanism from XINJI Company is analyzed by the proposed method. The drawbacks of dynamic performance are pointed out that the acceleration and apparent force had jumps in the running process. Finally, on the basis of existed problems, dynamic performance is modified by means of structural design of cam. The analytical results show that the angular acceleration's peak value of improvement mechanism has been decreased by 62%. Besides, the modified mechanism also expresses an excellent dynamic performance as the flat curve of acceleration, apparent force, contact force and hinge force.
