Abstract

The dynamic curving performance of rail transit vehicles operating with conventional, self-steered, and forced-steered trucks are analyzed. The influence of suspension design and wheel/rail profile geometry on vehicle dynamic response during curve entry is studied using a computer simulation model. The model incorporates wheel/rail creep force saturation, nonlinear suspension elements, rail lateral flexibility, and nonlinear wheel/rail geometry accounting for the possibility of two-point contact at any wheel. Curving performance is computed in terms of dynamic wheel/rail interaction forces, vehicle suspension and body forces, vehicle displacements and velocities, and wear indices such as the work done by creep forces in the wheel/rail contact patches.
