Abstract

Research purposes: Track irregularity is directly related to the subway train running stability and comfort. Track irregularity spectrums of different subway line conditions which contain ballastless track on elevated lines， ballasted track on ground lines and ballastless track on underground line were fitted and characteristics of which were compared for providing technical references to management of railway track quality and track dynamics analysis.

Research conclusions:(1)Track fitting spectrum using track irregularity spectrum model from China Academy of Railway Sciences and Levenberg-Marquardt method characterizes the original spectral characteristics well. (2)Subway track irregularity spectrum is with spectrum signature of broadband and narrowband random wave and some harmonic with complex periodic，different subway lines are with different spectrum signatures.(3)The condition of profile and align irregularity maintains well.(4)The research results could be used in track structure design and track maintenance.

Key words

Track spectrum / Levenberg-Marquardt method / track irregularity / power spectral density / curve-fitting
