Based on a practical mechanical press structural parameters, a dynamics optimization model of six-bar linkage is optimized by SiPESC. OPT, which is independently-developed optimization software for general purpose. A combined stochastic-gradient optimization method, combining genetic algorithm (GA) with sequential quadratic programming (SQP) algorithm and sequential linear programming (SLP) algorithm, is utilized for optimization calculation. The performance measures of the mechanical press, maximum speed of forging process and advance-to-return ratio, are improved.
