Forming Analysis for Automotive Fender Panel Considering Die Deformation

금형 변형을 고려한 자동차용 펜더 패널 성형해석

In order to see the effect of die deformation on the forming of sheet metal, the draw-ins, strains, and springbacks of an automotive fender panels are numerically simulated considering the die deformation found by the simultaneous structural analysis of press and dies. The comparison of the forming analysis result between the rigid die and the deformed die layout shows that the deformed tool provides more accurate forming and springback result.
