Thermal non-destructive characterization of rail networks by using Infrared Thermography and FEM simulation [PDF]

open access: yesMATEC Web of Conferences, 2022
Because of the repeated passage of trains, anomalies are created inside the rails in the form of cracks of different shapes and position. These are due essentially to the wheel – rail contact. They present a hazard causing at the final stage rail failure,

INFLUENCE OF CONTACT STATE ON PROPAGATION PATH OF RAIL SURFACE CRACK

open access: yesJixie qiangdu, 2022
In order to investigate the formation mechanism of fishhook shaped spalling defect on rail surface, the fatigue calculation model of wheel/rail rolling contact was established and the prediction method of crack propagation path was proposed based on the ...

MONITORING OF TRACK SECTIONS WITH LONG-PITCH CORRUGATION

open access: yesActa Polytechnica CTU Proceedings, 2016
The focus of this paper lies on monitoring of the track sections with rail corrugations caused by wheel sliding. Short waves on the running surface of the rail head on low rail are typical for this defect. Long-pitch corrugation is a significant cause of
