Experimental and numerical studies of the effects of a rail vibration absorber on suppressing short pitch rail corrugation [PDF]
, 2016 The effects of a rail vibration absorber on suppressing short pitch rail corrugation are studied. Firstly, a rail vibration field test is carried out to analyze the vibration response of the rail with and without the vibration absorbers.

Rail Corrugation: A Software Tool for Detection and Analysis Using Wavelets [PDF]
, 2018 Corrugation is an oscillatory wear of the rail and it is a consequence of the interaction between wheel and rail [1]. Rail corrugation usually appears in curves, but it may also arise in linear tracks.

A new perspective on rail corrugation and its practical implications
To investigate the possible formation and evolution mechanisms of rail corrugation related to the resonances of wheel and rail, a wave approach is adopted to characterize the wave propagation and vibration behaviour of the track.

Numerical prediction of rail corrugation growth on curves
, 2016 Rail corrugation (periodic surface irregularities at distinct wavelengths) is a problem experienced by many railway networks worldwide. Corrugation induces a pronounced dynamic wheel‒rail contact loading that leads to increased generation of noise and in
