RAIL CORRUGATION EFFECT ON VIBROACOUSTIC PROPERTIES UNDER STOCK OPERATION
Advanced Engineering Research, 2013 According to the papers of the German and French specialists, the rail corrugation stimulates increasing the rail sound radiation intensity. Besides, the consideration of the rail corrugation actually explains the high-frequency noise spectrum.

Corrugation-Induced Active Sites on Pristine Graphene for H2 Activation
, 2022 Pristine graphene is widely considered to be chemically inert, but recent experimental studies have suggested that it can provide frustrated Lewis pairs (FLPs) for activating H2 under mild conditions.

Detection of the Presence of Rail Corrugation Using Convolutional Neural Network
Engineering Transactions, 2022 Rail corrugation is a significant problem not only in heavy-haul freight but also in light rail systems. Over the last years, considerable progress has been made in understanding, measuring and treating corrugation problems also considered a matter of ...

Singing Corrugated Pipes [PDF]
American Journal of Physics, 1974 A corrugated tube open at both ends, with air flowing through the tube, sings notes which depend on the flow velocity and the length of the tube. The notes it sings are the natural harmonics of the tube. A given note will sing when the flow velocity is such that the “bump frequency” (frequency at which the air bumps into the corrugations) equals the ...

Theoretical analyses of growth mechanism of rail corrugation
Nihon Kikai Gakkai ronbunshu, 2019 Rail corrugation is a phenomenon in which roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running, and causes the vibration and the noise.

A Heavy-Haul Railway Corrugation Diagnosis Method Based on WPD-ASTFT and SVM
Shock and Vibration, 2022 Rail corrugation in heavy-haul railway increases the contact forces between the wheel and the rail and deteriorates the rail condition. Severe corrugation affects railway operational safety.

Mechanisms of short pitch rail corrugation
, 2022 Short pitch corrugation is a (quasi-) sinusoidal rail vertical defect on rail surface, and it was first found more than one century ago. The wavelength of short pitch corrugation is 20-80 mm, and its amplitude can be up to 100 µm.
