Abstract

Journal of Vibration and Control, Ahead of Print.
When trains pass through turnouts, the lateral vibration acceleration of the carbody (LVAC) often exceeds the permissible limit, with excessive wheel-rail wear being one of the causes of this phenomenon. Rail grinding is considered a potential solution, ...
