Data processing is important to the structure health monitoring system which produces large volumes of raw data containing the useful information and the noise. Wavelet analysis is a newly emerging theory in data processing field, which has good localization characteristics in both frequency and time domains compared to most traditional methods used for structural health monitoring. Wavelet can be...
With the development of manufacturing engineer, the aeroengine structure and operating condition have become more complex and the circumstance is generally under mal-condition with high temperature and pressure, so keeping its reliability and safety of airplane is essential. An effective method for aeroengine fault diagnosis using wavelet neural networks is proposed. The wavelet transform can accurately...
