On-board wheel-rail noise monitoring for the direction of track maintenance
An on-board wheel-rail noise monitoring system is reported that is capable of recording and qualifying overall wheel-rail noise, as well as identifying wheel squeal, flanging and impact noise from the background rolling noise. A GPS receiver is integrated to locate the noisy track sections. The integration of a yaw rate sensor allows the detection of curve radii and length. The on-board noise monitoring system can be used to direct track maintenance. One particular application is to correlate the identified wheel flanging noise to rail track lubrication condition. Field testing on a revenue-service train over a set corridor shows that ineffectively lubricated curves can be identified using the wheel flanging noise indicator.
