Railway applications - Acoustics - Rail and wheel roughness measurement related to noise generation
1.1 This document specifies a direct measurement method for characterizing the surface roughness of the rail and wheel associated with rolling noise ("acoustic roughness"), in the form of a one-third octave band spectrum.
This document describes a method for:
a) selecting measuring positions along a track or selecting wheels of a vehicle;
b) selecting lateral positions for measurements;
c) the data acquisition procedure;
d) measurement data processing in order to estimate a set of one-third octave band roughness spectra;
e) presentation of this estimate for comparison with limits of acoustic roughness;
f) comparison with a given upper limit in terms of a one-third octave band wavelength spectrum;
g) the measuring system requirements.
