THE APPLICATION OF HILBERT-HUANG TRANSFORM MARGINAL SPECTRUM-MAHALANOBIS DISTANCE ON THE ANALYSIS OF TRACK IRREGULARITY

Extracting the information of frequency-amplitude of the track irregularity through the Hilbert-Huang Transform（ HHT） spectrum,the clustering analysis is carried on the track irregularity HHT spectrum for the railways of same operating condition,then we can get the track irregularity marginal spectr...
