자동차 리어사이드 프레임에 대한 스프링백 특성연구
A Study on the Characteristics of springback about an automobile rear side frame
초록
Springback after forming is the critical factor affecting the product quality. It is very difficult to predict the amount of springback not only because of complex geometry and material characteristics of the stamping product but because the methodology has not been established. In this study springback mechanism is introduced and experimental tryout and computer simulation are carried out for die design of automotive rear side frame. Futher springback was verified by comparing the result of computer simulation with the measured tryout result.
