후방충돌 신 법규 대응을 위한 차체구조 고찰

In these day, various regulations continuously tightened for passenger protection. Moreover, NHTSA announced FMVSS No.301 Upgrade which described real world crash well. This final rule replaces the full rear impact test procedure with an offset rear impact test procedure specifying that only a portion of the width of the rear of test vehicle be impacted at 80 ㎞/h (50 mph). The new standard sets three separate limits on fuel spillage from crash-tested vehicles. The agency estimates that 46 percent of the vehicle fleet does not currently meet the upgraded rear impact test. This paper suggests the reasonable layout for protection fuel system through studying layout of other vehicles. We then study the body structures for improving crashworthiness by finite element analysis.
