Abstract

Journal of Vibration and Control, Ahead of Print.
In high-speed railways (HSR), rail over-grinding degrades the dynamic performance of vehicles, often causing the carbody lateral acceleration (CLA) to exceed safety limits. Rail grinding is an effective mitigation measure, but current engineering ...
