【Abstract】 Motion analysis of the dual-elbow-bar of Auto Die-cutting machine was carried out on the basis of the loop method and the numerical solution was worked out by the gradient method.The simulating motion curve of the dual-elbow-bar mechanism was drawn and its motion characteristics were analyzed.The optimum mathematic model of the mechanism was built and optimum design was made out then.The optimum results show that the idle stroke of the moving platform is reduced from 69.685 1 mm to 63.436 0 mm;the maximum alignment,on the horizontal direction of the moving platform,is also decreased from 0.954 3 mm to 0.774 7 mm;and the maximal inclination angle is reduced from 0.355 7°to 0.300 0°.更多还原
