Strength Assessment of Standardized Bogie Frame for Urban EMU

도시철도용 표준화 대차프레임의 강도평가

Nowadays domestic demands for urban EMUs are gradually increased due to traffic jams and environmental problems. Therefore it has been required to make sure of manufacturing quality and to acquire cost effective bogie frames through mass production. One of the major functions of bogie frames is to guarantee the static strength and durability. In this research, the comparison between FE analysis and actual load test results is performed for the bogie frame, which is manufactured by Rotem Company. The results show that the standardized bogie frame meets the strength requirements of domestic regulations.
