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 ...

A hypothesis on a wavelength fixing mechanism of rail corrugation

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2000
The mechanism of rail corrugation is analysed by a mathematical model in which a rail is represented as an infinite beam and a bogie as two point masses. The contact forces and the rate of increase in corrugation amplitude are calculated. The result shows that high growing rates occur in some velocity-wavelength regions, which nearly agree with ...

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,

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
