Investigation of the influence of rail pad stiffness on rail corrugation on a transit system

Wear, 2006
This paper presents a study on the influence of rail pad stiffness on rail corrugation in an underground line. The paper includes a theoretical analysis justifying the rationale behind the modification of the pad stiffness to reduce corrugation levels ...

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.

RAIL CORRUGATION IN THE PROCESS OF BRAKING

World of Transport and Transportation, 2017
[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT It was found in the course of the study that oscillations of the vehicle wheelset’s angular velocity during braking should be recognized as the principal cause of rail corrugation.

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 ...

Experimental study on mechanism of rail corrugation using corrugation simulator

Wear, 2002
This paper presents experimental study on corrugation phenomenon growing on the top surface of rail in a tight curve of track. One of the characteristics of the corrugation is to involve a slight slip, i.e. creepage, in rolling contact surfaces between rails and wheels.

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

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
