ACOUSTIC SIGNAL PROCESSING TO DIAGNOSE TRANSITING ELECTRIC TRAINS

In this paper, the authors describe a method that uses vibro-acoustic techniques for diagnosing defects on electric trains and other railroad components such as pantographs, electrical contact lines, rails, bogies, and wheels. The primary sources of acoustic vibrations come from vertical, longitudinal, and transversal stimuli. These stimuli in turn induce vibrations with different spatial configurations to the rail, while each vibration is resonant with a precise frequency. Diagnostic systems then extract, filter, and process the signal data. Results from experiment field tests validate the method’s performance.
