Application of Fractional Spline Wavelet in Detection of Abrupt Information from Fault Gear System

Abstract:

In this paper the Fractional Spline Wavelet Transform (FrSWT) is introduced based on the definitions and properties of the fractional B-spline and the symmetric fractional B-spline. Then the computation process and approximation properties of the FrSWT are also discussed and especially, the truncation error of computation is obtained analytically. At last, the FrSWT is applied to detect the abrupt information in the simulated and measured signal of fault gear system.
