Novikov V. Longer service life of rails with separate intermediate fastenings in curves. As a manuscript

The study deals with the solution to a longer operational life of continuous welded rails with the KБ-65 and CKД-65 intermediate rail fastenings on concrete foundation in curves with radii up to 450 m. It is achieved through scientifically substantiated requirements for the maximum safe track gauge. Especially, it is of great significance for sections with intensive side wear of continuous welded rails on concrete foundation in the curves with radii less than 450 m. The maximum permissible track gauge disregards rail foundation material, elastic parameters of intermediate rail fastening, new re-profiled wheels put into operation, operational factors impacting the physical state of intermediate rail fastenings, effect from braking modes of a locomotive regarding temperature deformations of wheel treads, excising tolerances taken during their production, lateral pressure of the track, etc.
