Finite element analysis of draw beads in deep drawing processes

الملخص EN

The design optimization of deep drawing process in manufacturing is proposed to control the final shape of the work piece after elastic spring back.

The manufacturing process design problem is formulated to minimize the difference between the shape of the desired work piece geometry and the final analysis.

This paper aims to predict the wrinkling and thinning (necking) failure and to study the effect of using draw bead on the thickness distribution along the cup.

In this paper to analysis the deep drawing process with draw beads the FEM code (ANSYS) version 12.1 packages is used, which is able to simulate various metal forming processes such as deep drawing.

The best results and the low variation between the maximum thickness and minimum thickness is found at the half circle shapes of Draw Bead and it’s about 10.4 % thinning and 26.5 % thickening.
