PRESS FORMED PARTS WITH REDUCED SPRINGBACK AND METHOD FOR FORMING THE PARTS |
| 摘要 |
A springback-reduced part formed by performing a springback reduction on a press-formed part that is formed by a press forming of a blank sheet made of a metal sheet. The springback-reduced part is formed by setting each element of an analytic model of the press-formed part to a stressed state that causes a springback, performing an optimization analysis for shape to detect a portion of the press-formed part that highly contributes to the rigidity thereof, applying a rigidity improving means on a specific portion of the press-formed part on the basis of the detected portion, and performing the press forming. |

1. A springback-reduced part formed by performing a springback reduction on a press-formed part, which is formed by a press forming of a blank sheet made of a metal sheet, wherein the springback-reduced part is formed by:
setting each element of an analytic model of the press-formed part to a stressed state that causes a springback; performing an optimization analysis to detect a portion of the press-formed part that highly contributes to a rigidity of the press-formed part; applying a rigidity improving unit on a specific portion of the press-formed part on a basis of the detected portion; and performing the press forming. |
