부재단면 형상에 따른 부재 굽힘붕괴 특성의 폼 충진 효과 = Foam Filling Effect on Bending Collapse Characteristics for Member Section Type

다국어 초록 (Multilingual Abstract)

More diversified and strengthened safety regulations require higher safety vehicle with less weight. The structural foam can play a role for restraining section distortion of main body members undergoing bending collapse at vehicle crash. In this study, using structural foam modeling technology, validated in previous work, the bending collapse characteristics were evaluated for two types of circular and actual vehicle body frame sections. With changing the foam filling method, outer panel thickness and section shape, load carrying capability and absorbed energy were observed. The results indicate valuable design strategy for effectively elevating bending collapse performance of body members with foam filled.
