Abstract
A new radial bogie named as a flexible coupled bogie with independently rotating wheels is put forward. By simulation analysis, the flexible coupled bogie surely takes on very good radial steering ability in complicated external condition. Contrast the flexible coupled bogie with the two-axle bogie and one-axle bogie, the dynamic performance of the flexible coupled bogie is provided with prominent dominance of the three bogies, which says that the new radial bogie with independently rotating wheels possess huge exploitation potential.
