Optimization of track parameters, considering their physical dispersion, to minimize rail corrugation

Abstract

In this paper, the influence on corrugation and therefore on the noise levels, of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been achieved. Finally, the influence of the dispersion of the track and contact parameters on corrugation growth has been studied. This work is based on the computer application RACING (RAil Corrugation INitiation and Growth) which has been developed by the authors to predict rail corrugation features. © 2008 Springer-Verlag Berlin Heidelberg.
