OPTIMUM BLANK DESIGN FOR DEEP DRAWING USING INTERACTION OF HIGH AND LOW FIDELITY SIMULATION

摘要

The design optimization system is developed using the interaction of high- and low-fidelity finite element simulations of a deep drawing process, and the multipoint approximation technique based on the iterative response surface building. The system has been applied to the optimum blank design for deep drawing process of a rectangular box to determine the optimum initial blank design that minimizes the waste of material. The blank design was optimized successfully in remarkably short computational time.
