MAGNETOELASTIC METHOD OF DIAGNOSTICS OF TECHNICAL CONDITION OF RAILWAY ROLLING STOCK WHEELS
(pp. 20-28)

Abstract. Detection of defects on the rolling surface of wheelsets, the formation of which occurs in the process of operation, is becoming the most important task of ensuring safety on railroad transport, the importance of which is becoming greater in connection with the growth of rolling stock speeds and increasing freight traffic. The development of defects in wheel pairs leads to destruction of the running parts of the rolling stock and wear of the rail tracks, and, as a consequence, an accident (railway derailment). One of the most significant characteristics of the condition of the tracks and rolling stock are the pressure of the wheel on the rail, and the load that occurs in the rail. Existing methods for identifying defects are reduced to measuring the deflection of the rail and weight measurement, which is used to judge the excess load created by the wheels of the rolling stock on the rail. This paper describes magnetoelastic methods for monitoring the condition of elements of railway tracks and rolling stock in front of existing non-magnetic ones. The advantage of magnetoelastic methods is that the determination of stresses in the object under study occurs directly, and not indirectly, because stress control is carried out by turning on the object under study as an element of the measurement circuit, which gives the most reliable ideas about the stresses arising in the object.

Keywords: railway transport, defect, magnetoelastic sensor, force, pressure, load, strain gages, magnetic permeability.
