On the Dynamic Ride Forces of the Vwhicle-Track System

This paper presents the dynamic ride forces generated at the wheel-rail interface during the running of a railway vehicle over a track with vertical irregularities derived from the overlying of the local discontinuities coming from the track joints and geometric irregularities. The dynamic ride for...
