The influence of friction coefficient and wheel/rail profiles on energy dissipation in the wheel/rail contact

This work investigates the energy dissipation in a wheel/rail system through friction work modeling. In order to identify the effect of the friction coefficient on the energy dissipation in the wheel/rail contact, several simulations were performed using a 3D multibody model of a railway vehicle implemented in the software package VI-Rail Adams,...

Effects of wheelset flexibility on the simulation of vehicle-track interaction at crossings

Though numerical models based on multi-body dynamics (MBD) are often used to simulate the vehicle-track interaction at crossing impact, their relative capabilities and accuracy were not discussed. This paper aims to investigate the influence of wheelset flexibility on the result of crossing impact simulation in the frequency range 0–500 Hz. Two...
