Abstract: The dynamic formulation of the electromechanical coupling system for a programmable mechanical press is studied. The dynamic model of two DOF seven-bar linkages is developed using Lagrange’s equation. According to the equivalent circuit of the dc motor and the brushless servomotor, their dynamic model and negative feed back model are developed separately. The forth order Runge-Kutta method, an explicit method, is chosen as the integration technique of computer simulation and the time history of the hybrid-driven press is obtained. Simulation results verified the feasibility of programmable mechanical press.
