Kinematic Optimization of High Speed Press Based on Genetic Algorithm and Differential Evolution

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.
