An Optimization Process of the Wheel Profile of Tramway Vehicles

Abstract This paper proposes, using mathematical models, an optimization process of the wheel profile of a tramway vehicle in order to ensure the operational requirements of the network (maximum speeds of 90 km/h on straight paths, negotiation of alignment curvature sections with very small radii (25 -50m)). The research covers tramway vehicles equipped with two different bogie technologies: a) bogies with independently rotating wheels, b) bogies of “mixed” behaviour. The results have evidenced that a) the choice of an optimal wheel profile with the help of mathematical models is theoretically possible b)the optimal wheel profile differs depending on the technology of the bogies.
