Impact Energy Absorption Characteristics of the Extruded Aluminum Sections for Rail Vehicles

철도차량 알루미늄 압출재의 충격에너지 흡수 특성

Extruded aluminum sections are used to the light construction of the rall vehicles structures However, the research works on the crashworthy design of the extruded aluminum sections are not published sufficiently in this paper, the impact energy absorption characteristics of extruded aluminum sections are investigated by crash simulation and test The optimized energy absorbing studies are also performed based on the selected design parameter variations of the sectional shapes and the dimensional ratios.
