Assessment of rail long-pitch corrugation

IOP Conference Series: Materials Science and Engineering, 2017
The paper focuses on defects of the running surface of the rail, namely the rail corrugation defect and specifically long-pitch corrugation in curves of small radii. These defects cause a shorter life of the rails, greater maintenance costs and increase the noise and vibration pollution.

Rail Corrugation Characteristics Deduced from a Wavelet Analysis of High-Speed Train Interior Noise and Vibration

Shock and Vibration
A method to deduce the characteristics of rail corrugation was developed and presented in this paper. It has been found that noise and vibration in the train vehicle were primarily contributed by rail corrugation and wheel polygonalisation.

Experimental Study on Vibration and Building Response Induced by Rail Corrugation in Metro Small-Radius Curves

Buildings
The vibrations induced by urban rail transit are exerting an increasingly prominent influence on the surrounding buildings and human health. As a prevalent track defect, rail corrugation can exacerbate the vibrations generated during train operation.

Study on the Influence of the Small Radius Curve Rail Corruqation on Locomotive Curve Passing Safety of Heavy Haul Railway

机车电传动, 2020
As the axle weight of the locomotive continues to increase, the wheel-rail wear is intensified, and rail corrugation on the small radius curve becomes more and more common.
