METHOD OF INERTIA MEASUREMENTS OF RAIL TRACK IRREGULARITIES

摘要

FIELD: railway transport; permanent way.;SUBSTANCE: invention relates to procedure of measuring rail track geometrical parameters. According to proposed method, vector of virtual speed in each rail line in designed system of coordinates is formed. Using signals from track pickups transfer from independent variable in time to independent variable in longitudinal coordinate of track is done. Vertical and horizontal profiles of rail lines are obtained by integrating found speeds. Sought for irregularities of rail lines are determined as difference between obtained profiles and their approximating curves obtained at processing of results of measurements and/or Certificate profiles. Transfer characteristic in proposed method does not depend on length of irregularities which excludes distortion of measuring information.;EFFECT: improved accuracy of measurements.;3 dwg
