Experimental Study on Controlling Rail Corrugation by Tuning Rail Damper

Applied Mechanics and Materials, 2014
At a serious rail corrugation line along Beijing metro Yi-zhuang line, one experiment of controlling rail corrugation has done. Based on the test and analysis of rail vibration decay rate, rail surface roughness and vibration acceleration on the rail and track bed before and after install TRD, it is concluded that install TRD on rail waist could ...

Surface analysis of corrugated rail treads

Wear, 1990
Abstract Corrugated rail treads were examined by surface analysis. The results led to the conclusion that the vibration of the wheel-tread system leads to different amounts of load at different areas of the surface. As a consequence there are areas with higher loads, higher deformation, higher hardening and higher wear resistance: the “hills ...

Impact of Dynamic Characteristics of Wheel-Rail Coupling on Rail Corrugation

SAE International Journal of Vehicle Dynamics, Stability, and NVH, 2019
<div>To gain a better understanding of the characteristics of corrugation, including the development and propagation of corrugation, and impact of vehicle and track dynamics, a computational model was established, taking into account the nonlinearity of vehicle-track coupling.

Study on Rail Corrugation Development Mechanisms

2021
On railway tracks, the corrugation that frequently occurs on the inner rails of sharp curves often results in noise and vibration. However, since there are no widely accepted theories on the evolution of such corrugation, nor countermeasures to prevent it, it is necessary to clarify the mechanisms governing rail corrugation development.

Effect of sleeper distance on rail corrugation

Wear, 1998
The present paper looks at the effect of sleeper separation on rail corrugation growth. The case under study involves short pitch corrugations on the low rail in sharp bends, the bends in question being those of metro-type railways in Bilbao, with the track on concrete slabs and with two resilient stages of STEDEF type.

Rail corrugation in The Netherlands—measurements and simulations

Wear, 2002
Abstract Rail roughness growth on Dutch railway tracks has been monitored since the early 1990s. On the track between Amersfoort and Baarn, significantly different levels of roughness have been detected on adjacent tangent track sections. The only obvious difference between two selected test sites located 250 m apart, one with a smooth rail and one ...

Rail Corrugation: Characteristics, Causes and Treatments

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 1993
Corrugation is a phenomenon which has excited the interest of railwaymen for more than a century, but for which there often does not appear to be a cure. It has generally been realized that there are in fact different corrugation mechanisms, and that some types of corrugation can indeed be prevented. The present paper draws upon both the literature and

The rolling of a wheel along a corrugated rail

Journal of Applied Mathematics and Mechanics, 2008
The rolling without detachment of a rigid massive wheel, carrying a static load, along a rail with undulations on the running surface, which arises as a result of non-uniform wear, is investigated. The rail is supported by an elastoviscous base. Because of the inertia of the wheel and the carriage the horizontal component of the velocity of the wheel ...

On residual stresses in corrugated rails and wheel/rail interaction

1992
In recent years the problem of rail corrugations has become more and more important. Thus, there is a strong need for reliable models describing this phenomenon. Several factors which influence the development of corrugations will be discussed, and the dynamic effects in wheel/rail rolling contact processes are considered.
