SPRINGBACK SUPPRESSION COUNTERMEASURE METHOD AND ANALYSIS DEVICE FOR PRESS-FORMED OBJECT

摘要

The springback suppression countermeasure method of a press-formed article according to the present invention is characterized by comprising an analytical model generating step of generating an analytical model of the part by using a planar element and / or a steric element, A stiffness-attributed-portion detecting step of performing a shape-optimizing analysis on an analytical model in which a stress state is set in the stress-state setting step to detect a high contribution to stiffness; And a stiffness improving step of taking a means for improving the stiffness of the part based on the part detected in the stiff contributing part detecting step.
