摘要：

In order to recover the self-centering ability for the independently rotating wheel running gear system, the method using lateral wheel-rail forces and yaw moments was proposed. Firstly, the self-steering principle was expounded in detail. The yaw aligning torque generated by the lateral wheel-rail force and the caster angle of yaw axis made contributions to the behavior that the independent wheels returned to the lateral position automatically. Furthermore, the arrangement was given out for the independently rotating wheel bogie. The two yaw axes of the front and rear wheel-pairs were v-shaped. Finally, the steering principle was validated by the multi-body dynamics simulation and the prototype testing. The results show that the independently rotating wheel bogie without caster angles can’t return to the track centerline. The low-frequency damped vibration appears in the lateral direction if the caster angle of the yaw axis is 5 or 10 degrees. The independent wheel automatically restores to the initial and lateral position in this case. Two kinds of hunting motions take place for the new independently rotating wheel bogie. The phenomenon of the wheel hunting motion from side to side occurs in the coasting test of the scaled bogie prototype. In consequence, the proposed steering method makes great contributions to the self-centering ability for the independently rotating wheel bogie. © 2023 Editorial Office of Chinese Journal of Mechanical Engineering.
