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

Integrated Floating Slab Dynamic Vibration Absorber Based on Tuned Liquid Particle Damping: Theory, Modeling, and Experimentation

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
As subway train‐induced low‐frequency vibrations continue to rise, there is an increasing need for more effective vibration control strategies. Although current low‐frequency vibration reduction methods offer some solutions, further progress is necessary.

Rail Corrugation Growth on Curves

, 2012
The development of periodic irregularities with distinct wavelengths (corrugation) on the low rail of small radius curves is studied through mathematical modelling, numerical simulations, field measurements and laboratory investigations.

Analysis of corrugation evolution characteristics based on scale-down tests – contact stick-slip perspective [PDF]

Railway Sciences
Purpose – Rail corrugation is still one of the unsolved challenges in the railway industry, and the abnormal vibration and high-frequency noise caused by it constitute serious adverse effects on the operating environment.

Crane Rail Health Monitoring With Laser Vibrometry

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
This paper proposes a method for the evaluation of the combined system of heavy port cranes and the rails on which they run and demonstrates its success. Using techniques from railroad track health monitoring, we record the guided waves created in the rails from the movement of the wheels using laser‐based vibrometry.

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

Rail Corrugation Characteristics Deduced from a Wavelet Analysis of High-Speed Train Interior Noise and Vibration

Shock and Vibration
A method to deduce the characteristics of rail corrugation was developed and presented in this paper. It has been found that noise and vibration in the train vehicle were primarily contributed by rail corrugation and wheel polygonalisation.

Experimental Study on Vibration and Building Response Induced by Rail Corrugation in Metro Small-Radius Curves

Buildings
The vibrations induced by urban rail transit are exerting an increasingly prominent influence on the surrounding buildings and human health. As a prevalent track defect, rail corrugation can exacerbate the vibrations generated during train operation.

Study on the Influence of the Small Radius Curve Rail Corruqation on Locomotive Curve Passing Safety of Heavy Haul Railway

机车电传动, 2020
As the axle weight of the locomotive continues to increase, the wheel-rail wear is intensified, and rail corrugation on the small radius curve becomes more and more common.
