Analysis of vibration transmissibility of railway vehicles while transiting curves with lateral track irregularity

This paper describes an investigation into the vibration characteristics resulting from lateral track irregularities that are transferred and become lateral vehicle vibrations when a railway car transits a curved section of track. These transfer characteristics are derived via vehicle dynamics simul...
