Study on synthetic analysis system for track irregularity

One of the necessary conditions of ensuring the safe run of railway is to evaluate rationally and all-roundly the regular situation of railway track. On the basis of the study progress on track spectrum,a synthetic analysis system was set up to analyze track irregularities by the design thought that system function was fulfilled through modules. The system contained 8 modules, they were the data collect module of track irregularities, the analysis module of existing technology of track irregularities, the analysis module of power spectrum density (simplified as PSD)of track irregularities, time and frequency analysis modules on track irregularities, the analysis module of vehicles messages, the analysis of predicting the developing trend of track irregularities, the synthetic evaluation modules of track irregularities and the maintaining plans module of railway irregularities. An example was given, which was that the design and fulfillment of the analysis module of PSD of track irregularities were expounded. The module contains 3 sub-modules, such as data input, calculation and evaluation of track spectrum.
