METHOD FOR CONTROL OVER LONGITUDINAL STRESS CONDITION OF RAIL BARS IN CONTINUOUS WELDED RAIL TRACKS Russian patent published in 2015 - IPC B61K9/08 G01L1/00 

FIELD: electricity.

SUBSTANCE: longitudinal stress values are defined continuously during the motion of a rolling stock at the mechanical interaction of a rolling railroad wheel with a rail when mechanical oscillations are excited at tested sections of rail bars with recording, converting of the received oscillations to acoustic oscillations with signal amplification, and at the analysis of spectrum of the excited oscillations in frequency and amplitude depending on a value of longitudinal mechanical stress at the rail bar sections. According to results of data processing changes in the spectrum of the excited oscillations are analysed and sections of railroad tracks are identified with deviations in an amplitude-frequency curve in a real-time mode.

EFFECT: increased efficiency of control and safety of train traffic.
