초록

Laser welded tailored blanks(TB) are increasingly used in automotive parts. Among these, TB side panel has forming difficulties in stretch flanging areas such as front and center pillar lower region. To avoid splits in the stretch flanging areas, Proper design of blank shape and drawbeads are essential In this study, the forming simulaton is carried out to investigate the influences of blank shape and drawbeads on stretch flange formability of different thickness TB. And an optimization procedure including the effects of both the blank design and drawbeads is presented. The optimization procedure proposed in this study is expected to be effectively used in blank and die design of TB side panel.
