Railscan: A Tool for the Detection and Quantification of Rail Corrugation
Abstract : Rail corrugation is a phenomenon that leads to a
waving in the rails with wavelengths typically between 3 cm and 100 cm
and amplitude levels of several microns. The genesis of this waving is
complex. Rail corrugation is a recognized problem that leads to excess
vibration on the rails and vehicles to a point of reducing their life
span and compromising safety. In urban areas excess vibration noise is
also a problem. A software tool was developed to analyze accelerometer
signals acquired in the boggies of rail vehicles in order to quantify
the rail corrugation according to their frequency and amplitude. A
wavelet packet methodology was used in this work and compared with the
One Third Octave Filter (OTOF) power representations, which is currently
used in the industry. It is shown that the former produces better
results.
