Study of Melting Methods by Electric Resistance Welding of Rails

open access: yesMetals, 2022
An analysis of the results of rail operation shows that up to a third of all rail breaks in the railway line and up to 12.9% of all withdrawn acute defective rails are associated with welded joints.

Features of the influence of intermediate rail fastenings on the operational durability of rails

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2021
Heat-strengthened rails of the R65 type are the main type of rails used on the railway network of Russian Railways. Reducing the number of cropped and acutely defective rails is possible due to the rational use of the design features of intermediate rail

Technical requirements for the selection of rail grades [PDF]

open access: yesTehnika, 2022
The most common types of rail defects on modern railway lines occur due to the rolling contact fatigue of rail steel. One of the methods to slow down the development of these rail defects is the application of new steel grades with increased hardness in ...

Assessment of the risk of contact fatigue damage in wheels and rails using the Dang Van criterion

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2023
Introduction. Dynamic loads cause high contact stresses in the materials of wheels and rails, which leads to their wear and accumulation of contact fatigue damage. A number of approaches were proposed for calculations of contact fatigue and prediction of
