| Abstract: | Short wavelength irregularity of rail surface is the main reason of vibration and noise of railway alongside vicinity. Based on the continuous measurements of rail irregularity on one of the lines in Shanghai urban rail transit,and referring to the EU Standard of roughness levels of measuring noise emitted by rail bound vehicles and the acceptance of rail grinding,milling work in track,this paper evaluates the characteristics of short wavelength irregularity of rail surface in time and frequency domain,and ... |
