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.

Considerations on Rail Corrugation

Vehicle System Dynamics, 1994
SUMMARY The paper consists of three parts 1.Description of a One-Dimensional Corrugated Surface The surface is modelled as a periodic, differentiable function of the distance traversed. Three criteria of corrugation growth are developed 2. The Frequency Response of Wheel and Rail A linear relationship is assumed between the Fourier transforms of the ...

Systematical Analysis of Rail Corrugation in Urban Rail Transit

Journal of Convergence Information Technology, 2013
Abstract Rail corrugation is an adulatory wear which is similar to wave in shapes that can be observed on the rail rolling surface along the longitudinal direction after the rail is put into use. In this paper, a vehicle-track coupled finite element model is established to analyze the reason of rail corrugation systematically in urban rail transit. The

A linear model for the corrugation of rails

Journal of Sound and Vibration, 1991
Abstract A linear model for the corrugation of rails is described. The study of a transfer function between the initial wheel and rail roughness and the wear rate spectra in the contact patch is presented. Under some conditions, depending on mean creepages, wheelset and track parameters, the initial roughness on the rail is shown to degenerate into ...

Shakedown of Rail Corrugations

1995
A model of the elastic-plastic behaviour of a rail under moving and cyclically changing loads is proposed. Simple analytical expressions enable us to estimate the changes of the limit shear stress and residual stresses under the running rail surface after repeated passages of a wheel. It is shown that magnitudes of local hardening and residual stresses

Effect of a scratch on curved rail on initiation and evolution of rail corrugation

Tribology International, 2004
Abstract The effect of a scratch formed on the running surface of a curved rail, due to the slide of a locomotive wheel, on the formation and evolution of rail corrugation is investigated in detail with numerical methods when a wheelset is steadily and repeatedly curving. In the calculation we consider a combination of Kalker’s rolling contact theory

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 ...

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.

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 ...

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 ...
