IMPROVEMENT OF THE TEMPERATURE CONTROL METHOD FOR RAILS AND RAILS STRINGS OF THE CONTINUOUS WELDED TRACK
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 174, Issue 8
Abstract
Modern methods of rail temperature control were studied based on the analysis of the existing regulations regarding arrangement, repair and routine maintenance of continuous welded track and their shortcomings and errors were determined; a new method of thermometric studies using the special test bench which is supposed to reconstruct as much as possible eventual climatic operation conditions of strings of rails was proposed to eliminate those shortcomings and errors. The rails to be studied should be fastened at the bench using the rail fastenings on the semi-ties in the track bed with the dimensions in accordance with the applicable regulations, on the roadbed, for the most reliable reconstruction of the heat exchange processes between the air, the track bed surface and the rail fastenings. At the first stage, KB-65 intermediate fastenings as the most common ones for continuous welded track are supposed to be used as fastenings, and KPP-5 fastenings are supposed to be used further.
