In this study, an active steering bogie with a re-designed primary axial rubber spring for urban trains was developed. The applied axial rubber spring had a reasonable stiffness that can be achieved in the X, Y and Z directions. Therefore, the steering performance of the bogie can improve because of the lower longitudinal stiffness. The running performance of an active steering vehicle on a curved track was simulated by means of a co-simulation with VI-Rail and MATLAB/Simulink. Further, a control algorithm was developed and applied to an actual active steering bogie. The radius of curvature acquired from the actual active steering bogie by the control algorithm was in reasonable agreement with that acquired from a track inspection vehicle. The numerical analysis revealed a significant improvement in the vehicle safety and ride quality and a reduction in the wheel-rail wear and noise. As a result, the validities of the developed primary suspension and control algorithm of the active steering bogie were confirmed. Further, this study may enable railway vehicles to run more stably and faster on sharp curves.
