This study focuses on theoretical analysis of curve negotiation of rubber-tired trams and its verification. The architecture and key technical parameters, as well as the working principles of the guiding mechanism and articulated mechanism are introduced and analyzed using kinematic theory. Freedom of structural motion and kinematic relationships of running gear and carbody are elaborated under the climbing (gradient of 13%) working conditions with the minimum horizontal curve radius (R=15m), S type curve as well as minimum transition curve radius (R=200m) through Dynamics of Multi-body System of SIMPACK and MSC ADAMS. A curve negotiating test is carried out on 3-car prototype tram to verify that the vehicle meets the top index of specification. Finally, the simulation analysis is compared with the experimental results to confirm that the simulation calculation is consistent with that under test condition.
