Collapse Characteristics of Aluminum Extruded Sections and Crash Analysis Using Half Scale Model

알루미늄 압출재의 붕괴 특성 및 축소모형을 이용한 충격 해석 기법 연구

The aluminum extruded sections are used to the light construction of the high speed rail vehicle structures. However, the research works on the crashworthy design of aluminum extruded sections are not published sufficiently. In this paper, the collapse characteristics of aluminum extruded sections are investigated by crush test and simulation. The scale model studies are also performed to predict the impact energy absorption characteristics of full scale model through axial crush test and simulation.
