Resonant signal analysis-based inspection of rail components

摘要

A solution for evaluating the condition of a rail component based on resonant response profiles across a set of bands of vibrations. The vibrations can be induced into the target component during normal operation of the target component. The resonant response profile of the rail component can vary depending on wear or damage, and thus can be used to determine whether the rail component can safely remain in use. An embodiment comprises an isolated segment of rail of a length selected to allow a single railroad wheel on it at a time, with a set of devices which can acquire the resonance signals from the wheel.

1. A method for resonant signal analysis-based inspection of a rail component, the method comprising:
detecting and recording resonances produced by vibrations of a spectrum of frequencies in an in-situ rail component as resonance data; determining a set of characteristics of resonant peaks within each of a plurality of frequency bands of interest across a wide range of frequencies of the resonance data; comparing the set of characteristics with an expected resonance profile for the rail component, wherein the expected resonance profile includes a set of expected characteristics for each of the plurality of frequency bands of interest; and determining a condition of the rail component based on the comparing.
