능동조향대차용 액슬 박스의 강도 및 피로해석

초록

Recently, a lot of study about active steering bogie which can control steering on the small curve rail has been progressing. Compared with existing bogie, active steering bogie decreases wear and noise between wheels and rail. Also it improves running safety and curving performance. In this study strength analysis of axle box in the active steering bogie was performed using the finite element method. Also fatigue analysis of axle box under variable loading was performed. Finally, structurally stable axle box on the curve rail was designed by modifying design.
