Modeling of high-speed wheel-rail rolling contact on a corrugated rail and corrugation development [PDF]
Journal of Zhejiang University Science A, 2014 Short pitch rail corrugations were observed on a recently opened Chinese high-speed line. On the basis of field measurements and observations of corrugations occurred on the high-speed line, a 3D transient rolling contact model is developed using the explicit finite element (FE) method to investigate high-speed vehicle-track interactions in the ...

Applied Sciences, 2023 Rail corrugation is a degradation phenomenon that manifests as a quasi-periodic irregularity on the running surface of the rail. It is a critical problem for urban railway lines because it induces ground-borne vibrations transmitted to the buildings near

The Interaction Between Railway Vehicle Dynamics And Track Lateral Alignment [PDF]
This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates.

The development of rail-head acoustic roughness
, 2009 A model of the development of rail-head acoustic roughness on tangent track has been formulated. The model consists of a two-dimensional time domain wheel-rail interaction force calculation, with the normal force used as the input to a two-dimensional ...

Dynamic characteristics and growth curve of rail corrugation at saturation stage
Nihon Kikai Gakkai ronbunshu, 2021 Rail corrugation, which causes the vibration and the noise, is a phenomenon in which roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running.
