Dynamic optimization of track components to minimize rail corrugation [PDF]

, 2009
In this paper, the influence on corrugation 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

Prediction of Rail Corrugation Growth and Rail Wear Rate using Three-Dimensional Finite Element Analysis

, 2018
Rail corrugation is a typical rail surface defect that can reduce rail service life and increase maintenance costs. Manifested as undulating wears on rail surface, the formation and growth of rail corrugation relies on a combination of wheel-rail dynamic

Acoustic vibration characteristics for combined diagnosis of rail corrugation: An application of MCiSSA and permutation heterogeneous recurrence plot

Results in Engineering
In this paper, we utilize acoustic vibration characteristics for the combined diagnosis of rail corrugation. The two-dimensional signal is first decomposed into several modes by Multivariate circulant singular spectrum analysis (MCiSSA) and the ...
