고강도 열연 강판 적용 단판형 로어암
1-Piece Typed Lower Control Arm Using High Strength Hot Rolled Steel Sheet
초록
As one way of weight saving of the vehicle, 1-piece typed lower control arm has been developed using high strength hot rolled steel sheet. In order to overcome the edge splitting problem during edge flanging or burring process, HER (hole expansion ratio) value of steel sheet was primarily considered. The strength grade of steel sheet and the shape were optimized utilizing Taguchi method.
