In order to improve the dynamic performance of driving system of the servo press, the structure sketch of the crank-toggle link transmission system was established, and the geometric parameters mathematic model of this system was established by the vector equation. Then, the mathematical equation of equivalent rotating inertia was established based on its transition condition, and the mathematical model of this mechanism was established with software MATLAB. Furthermore, the amplitude curves of equivalent rotating inertia were obtained by analyzing the different stroke lengths of this system, and the acceleration and deceleration performance curves of crank were analyzed under the servo motor constant torque output. The analysis results show that the inertia of the mechanism can be reduced obviously, the angular acceleration of the crank is increased and the dynamic performance of this system is improved by reducing the stroke length of this system.
