DIAGNOSTIC SYSTEM wheels and axles of wagon wheelsets BY multi-angle acoustic holography

摘要

Automated diagnostic system of wheels and axle wheelsets wagons by multi-angle Acoust. holography solves the problem of increasing the sensitivity and reliability of the control wheel and axle wheelsets wagons under depots by identifying defects at an early stage of development to measure their size and location, which increases the accuracy of calculation of the residual life wheelsets. The system includes a computerized mobile rack (8) that controls the rotation of the wheelset and coupled to the mounting stand (9) arranged thereon system couplant supply, two fixed scanners wheels (12) and a movable scanner wheelset axis (13) mounted with the possibility of movement along the axis, wherein the scanners are provided with piezoelectric shirokoraskryvnymi. converters whose inputs and outputs through the electronics unit (44) and the high frequency signal switching unit (14) connected to the analog-digital module (23) inputted with the composition of the system unit movable rack. To the respective outputs of the system unit connected to the displacement sensor interface module (18) and an interface converter (17) connected through a software module control circuits moving the scanner wheelset axis and its rotation. 4 ill.
