چکیده مقاله:

In this paper, a die shape optimization method for reduction of spring back defect due to elastic recovery behavior in explosive deep drawing process is presented by using the reduced basis technique coupled by finite element and design of experiments methods. The primary objective of the proposed method is to reduce the enormous number of design variables required to define the initial die shape. The reduced basis technique is a weighted combination of several basis shapes. The aim of the method is to find the best combination using the weights for each shape as the design variables. The experimental design of Taguchi method is used to build the approximation model and to perform optimization. This method is demonstrated on the die shape optimization of deep drawing of a trapezoidal cup.
