Design & Simulation of Draw Bead Profile Sunil Mahajan

The quality of sheet metal component is secured by the material flow into the die cavity. Draw beads are usually used in sheet metal forming to restrain the sheet from flowing freely into die cavity. In this book, finite element method is used to improve the location of a draw bead and analyses the strain and thickness variations during the panel header drawing process. In proposed project draw bead is added to the blank holder to reduce the thinning effect of blank caused due to forming process. Altair's HYPERFORM and Radioss solver commercially available for simulation and analyzing the forming process. By using draw bead and forming parameter such as blank holding force, coefficient of friction therefore tendency of wrinkling and thinning reduced.
