Abstract

Welded blank hydroforming technology is applied to an automotive subframe which has been manufactured by stamping and welding processes. Blank shape and die system is suggested on the basis of finite element analyses. Various defects, especially wrinkling problems in the area of sudden section change, are investigated, analyzed and tried out. The blank shape and the die system are modified to get the sound welded blank hydroformed subframe.
