Effect of Track Support Structures on Friction‐Induced Vibrations of Wheelset‐Track Systems
Shock and Vibration, Volume 2023, Issue 1, 2023., 2023 The aim of the present investigation is to study the effect of track support structures on the metro 5th to 8th‐order out‐of‐round (OOR) wheel caused by friction‐induced vibrations. Three finite element models of metro‐leading wheelset‐track systems with three types of track support structures were established.
