Kinematic Optimization of a New High-Speed Press Using a GA-DE Algorithm

The objective of this paper is to implement the optimal design of a high-speed press with a new transmission mechanism for punching. Firstly, the novel mechanism is shown and its merits are discussed. Then kinematic analysis is carried out by using the vector loop method. Additionally, the kinematic dimensions of the mechanism are derived by using a GA-DE algorithm. Finally, a comparative study for kinematics is made between original and optimized dimensions. The results indicate that proposed novel mechanism with optimized kinematic dimensions is of better output motion for high-speed punching.
