Abstract
The establishment of an effective track maintenance method is a very important issue for the stability, of train riding comfort, cost reduction management, and soon. This paper examines the “Wavelet theory” as an analyzing tool for detecting specified information of the track such as evenness-irregularity data. Moreover, space-frequency and multiresolution analysis are performed using the trackirregularity inspection data at the medium wavelength domain. And the potentialities of this theory of the future evenness evaluation methods are discussed. Furthermore, the self-similarity and the process of deterioration and restoration on the tracks are discussed by the continuous wavelet transform.
