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.

Transverse Oscillation of a Base Slab Section of Ballastless Track
World of Transport and Transportation, 2019 The study is devoted to construction of a mathematical model of a slab of a ballastless base of a railway track, assembled from separate segments fastened together. Each rectangular segment is modeled by a transversely isotropic prestressed plate. An equation has been obtained that allows researchers to study the natural oscillation frequencies of a ...

Ballastless track support deterioration evaluation using machine learning [PDF]
, 2023 Ballastless tracks have been widely used for highspeed rail systems globally since their maintenance is relatively minimal. However, support deterioration right beneath the inbetween slabs’ connectors has been usually reported and quite well known in the

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Line shape control is the most critical step in the construction of high‐speed railway bridges. The deflection of long‐span bridges (such as cable‐stayed bridges) is more complex as a multipoint elastic‐supported system, especially during track slab construction.
