Abstract

Journal of Vibration and Control, Ahead of Print.
Train passage through turnouts induces significant vibrations in urban rail transit systems, particularly under diverging-route operation with small-radius curves. Such curves generate pronounced centrifugal forces, amplifying structural responses. To ...
