| Abstract: | The novel transmission mechanism of high-speed press which ensures inertial balance was proposed. For the deficiency of optimum algorithm, a hybrid algorithm combining genetic algorithm with differential evolution was presented and its scheme was stated. Then the mechanism was simplified and optimization model was established. A comparative study for kinematics was made between original and optimized dimensions by the GA-DE algorithm. As the result shown, the optimized mechanism is of better output motion for high-speed punching, which indicates the algorithm is highly effective. |
