Abstract

Abstract

In order to reasonably control the position clearance of vehicle wheelsets, improve the lateral dynamics performances of vehicle with magneto-rheological fluid (MRF) coupled wheelsets at high speed, a spatial dynamics model of vehicle was established, and the longitudinal position clearance influence of vehicle wheelsets on the critical velocity and curve passing performances of vehicle were analyzed.Analysis result shows that the clearance increase can make vehicle critical velocity descend sharply, make the lateral displacement and attack angle of wheelsets, the lateral force of wheel/rail and lateral acceleration of carbody largen rapidly; vehicle has higher critical velocity and better curve passing performances only in the condition of small clearance.
