Determination of Shape and Position for Reinforcement Blank at Simultaneous Forming of Automotive Side Member

자동차용 사이드 멤버 일체복합성형시 보강판재의 형상 및 위치 결정

New forming technologies are being introduced to automotive manufacturing processes. Among them, a simultaneous forming is one of the innovative forming technologies to be able to reduce production time and cost. Several parts can be simultaneously manufactured by the process, while the conventional stamping demands the same number of die sets with the number of parts. In this study, the automotive rear floor side member was manufactured by the simultaneous forming. The position and the size of initial blank were determined by forming analyses and try-outs, and the blank movement during the forming was controlled by introducing the spotweld.
