METHOD FOR DETERMINATION OF ACTUAL TEMPERATURE OF ANCHORING OF RAIL BED Russian patent published in 2021 - IPC E01B35/00 B61K9/08 

FIELD: rail vehicles.

SUBSTANCE: invention relates to control of railway track condition and can be used for determination of actual temperature of fastening rail track of continuous rail track during repair works. Method of determining actual temperature of fixation of rail string is that twice determined intensity of generated Barkhausen noise in relative units, first time, at current temperature of rail string, on rigidly fixed section, on which it is necessary to determine actual temperature of fixation of rail, at which laid rail track, second time intensity of generated Barkhausen noise is determined at current temperature of rail string, at end section of rail string, on which longitudinal movements caused by daily and seasonal temperature drop are realized. Actual temperature of the generated Barkhausen noise and the data on the current rail temperature are programmed to calculate the actual temperature of fixation of the rail.

EFFECT: as a result, safety of railway traffic movement is improved, determination of actual temperature of uninterrupted rail track laying is simplified.
