Curving performance evaluation for active-bogie-steering bogie with multibody dynamics simulation and experiment on test stand

The authors propose a new concept of the active steering bogie. which has simple mechanism and high curving performance. Active-bogie-steering bogie has the steering mechanism only between car-body and bogie frame and no mechanism in wheelsets. On curved track, the bogie frames are steered toward,; radial steering direction by actuators according to active control law. In this paper, we show that the lateral contact force of the leading-outside wheel call be reduced to zero even on very sharp curve by this mechanism. Validity tests were carried out by Using a full-size test bogie on the Tolling test stand, which can simulate curve-running condition. Bogie parameters and steering actuator characteristic; are identified in order to compare the experimental results with multibody dynamics simulation. After these stand tests and simulation, We successfully verified the effectiveness of the proposed bogie mechanism and control.
