Abstract

In this paper, a new simulation program specifically designed for tramcar vehicles is presented. The proposed numerical model allows the most common tramcar configurations to be reproduced and the vehicle performance to be analysed in terms of combined longitudinal, lateral and vertical dynamics. A particularly detailed procedure for the calculation of wheel-rail contact forces is implemented, thus allowing a deep investigation of sharp curve negotiation behaviour and its effect on vehicle safety, comfort and wheel/rail wear and fatigue. The simulation software also allows the state equations of the traction motors (together with those of the electric converters) to be considered in order to analyse the electro-mechanical interaction of the two subsystems in transient conditions, and to compare/optimise different vehicle control strategies. The main software features are summarised, together with their theoretical basis, and some numerical results are reported, in comparison with the corresponding experimental data.
