후륜 현가장치용 부재의 튜브성형기법 개발
Development of the Tube Forming Method for the Cross Member of a Rear Suspension
초록
Tool design is carried out for a press forming of a cross member in the rear suspension assembly based on the result of the finite element analysis. The analysis simulates the two-stage stamping process with the initial design and it fully reveals the unfavorable mechanism which develops inferiorities during forming. In this paper, a new design guideline is proposed to modify the process and tool shapes for a single-stage forming process. With the improved tool design, this study fabricates prototypes that satisfy the durability requirement.
