Review on rail corrugation studies

Wear, 2002
In Japan, rail corrugations had not been so serious formerly, but it began to be prevailing in recent years. In order to prevent the generation of rail corrugation, many studies have been reported in the world since the end of 19th century, but theories on them have not explained the formation mechanism perfectly and no perfect countermeasures have ...

Short pitch corrugation mitigation by rail constraint design

International Journal of Mechanical Sciences, 2023
Short pitch corrugation is a quasi-periodic rail defect that induces a high level of noise and accelerates track degradation. This paper proposes a methodology to mitigate short pitch corrugation by rail constraint design, including four steps. In Step 1,

Field measurement and model prediction of rail corrugation [PDF]

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2020
In a field test, three corrugation profiles of rails and their corresponding vibrations were measured, and the wavelengths and frequencies of rail corrugations were obtained.

Rail corrugation detection by Gabor filtering

Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
Inspection of the rail state in order to detect defects is one of the basic tasks in railway maintenance. Rail defects exhibit different properties and are divided in various categories relating to the type and position of flaws on the rail. We propose a technique, based on texture analysis of the rail surface, to detect and classify a particular class

An experimental study of rail corrugation

Wear, 2003
Abstract This paper presents experimental study of rail corrugation using a JD-1 wheel/rail simulate facility, which mainly consists of a big wheel serving as the rail, and a small wheel serving as the locomotive or rolling stock wheel. The power delivered to each testing wheel can be accurately controlled.

Analysis of rail corrugation in cornering

Wear, 2008
Rail corrugation in cornering is examined via a non-linear time-domain model of a bogie cornering. The model is computationally fast due to a modal description of a wheelset that includes bending and twisting modes of its axle as well as flexing of wheel hubs.
