충격압궤 실험에 의한 경량화용 차체 구조부재의 개발 = Development of Structural Members for a Use of Lightweight by Impact Collapse Experimentation

다국어 초록 (Multilingual Abstract)

The most important requirement in the initial design stage of vehicles is that the structural members of a vehicle body adequately absorb impact energy and secure a safe space during collision. Furthermore, it is the development of materials for weight reduction. Therefore, the collapse characteristics caused by the collision of the structural member having the largest collision energy absorption must be accurately understood when designing a vehicle in consideration of a safe and lightweight design. In this study, the impact collapse experiments were conducted after designing, manufacturing, and molding single hat and double-hat cross-section members of steel and carbon fiber reinforced plastic(CFRP)/epoxy materials. By examining the resulting energy absorption characteristics, accurate design data could be obtained to develop the side structural members for optimal lightweight vehicles.
