The Pretreatment and Time Domain Analysis of the Track Long-Wave Irregularity Testing Data in Maglev Railway Based on Magnetic Mechanics

Abstract:

In digital signal analysis, the signal needs to be pretreated first. Because there are many uncertain factors affecting the signal in the engineering projects and the signal analysis methods are different too, the signal can be characterized through pretreatment so that the processing methods will be selected accordingly. This belongs to signal processing qualitative part. On the other hand, through pretreatment the abnormal signals caused by the machines or people error can be removed. This belongs to signal processing quantitative part. After the pretreatment of the track long-wave irregularity testing data in the maglev railway, the signal is determined as non-stationary stochastic data. According to property of the data, modern signal time-frequency analysis method was applied in this article for further study.
