【Abstract】 A mechanical press driven by hybrid mechanism was developed,that considered the displacements and velocity requirements of press technology. The analyses of forward kinematics and the optimum model were set up. The actual displacement curves of slide can approach to the ideal ones by two step optimum. The dimension of the linkages and the motion rules of servomotor has been optimized. Therefore, by rightly designing the input motions of servomotor, the slide can pass through a group of more desired trajectories. In the end,advantages of the hybrid-driven mechanical press were analyzed.更多还原
