    Abstract
  • In order to get the track spectrum that reasonably indicates the irregularity character of main line railway in China, a fitting approach of track spectrum was set up. In the approach, track irregularity data were computed to get track spectrum, track spectrum was preprocessed by using smoothness method and interpolation method, the effect of biggish salient waveforms on track spectrum was decreased by using simple elimination method, every adjacent 3-point average method and envelope-average method, the fitting precision of track spectrum was improved by using cubic spline interpolation method, and track spectrum was fitted by using nonlinear curve-fitting optimization algorithm in the least-squares sense. Fitting result shows that fitting track spectrum can accurately indicate the track irregularity character of main line railway in China, so the approach is feasible.
