범퍼 레일용 롤포밍 성형의 공정 변수 영향도 해석

다국어 초록 (Multilingual Abstract)

The roll-forming process is often used to manufacture long, thin-walled products such as a pipe. The final cross-section is a comparatively simple open-channel, a closed tube section or a complex profile with several bends. In recent years, that process is often applied to the bumper rail in the automotive industries. In this study, a optimal roll flower model and proper roll-pass sequences can be suggested by analyzing total effective strain, thickness and longitudinal strain according to the roll-pass with FEM simulation. And also effects of the process parameters on the final shape formed by roll forming defects a evaluated.
