Abstract：

For the characteristics of two degrees of freedom for servo mechanical press with dual-drive toggle mechanism and, the main toggle system of dual-drive toggle mechanism was decoupled by backward induction design principle, and the design analysis of adopting the bottom center of slide as the starting point was conducted. Then, the mathematics computing model of kinematics and dynamics was built by vector equation analytic method and dynamic statics method. Furthermore, the multi-objective function of kinematics and dynamics of main toggle system was optimized by MATLAB′s optimization toolbox, and a set of parameters which meet the demands of small speed fluctuation and low driving torque of slider was obtained. Finally, the existing isometric toggle mechanism, triangle toggle mechanism and dual-drive toggle mechanism were simulated by software ADAMS, and the working condition of slider and torque needed by crank were compared and analyzed. The conclusion shows that the dual-drive toggle mechanism satisfies the requirements of servo press.
