Hilbert-huang transform and the application
WebThis paper put forward a method which is based on Fast Fourier Transform (FFT) and Hilbert Huang transform (HHT) to improve the accuracy of modal parameters identification. Firstly, FFT was used to determine the approximate range of each natural frequency, and then filter the signal by the bandwidth filter in order to reduce the effects of noise and … WebA Refined Hilbert–Huang Transform With Applications to Interarea Oscillation Monitoring

WebHilbert-Huang Transform,which was developed by Norden E Huang of NASA in 1998,is a new meth- od of Time-Frequency analysis.The major parts of this method,empirical mode … WebThe Hilbert–Huang transform (HHT) is an empirically based data-analysis method. Its basis of expansion is adaptive, so that it can produce physically meaningful representations of data from nonlinear and non-stationary processes. The advantage of being adaptive has a price: the difficulty of laying a firm theoretical foundation.
WebOct 20, 2008 · A new approach to fault diagnosis of gear crack based on ensemble empirical mode decomposition (EEMD) and Hilbert-Huang transform (HHT) technique is presented. Firstly, the time-domain vibration signal of the gearbox with gear crack fault is measured. Then the original vibration signal is separated into intrinsic oscillation modes, using the … WebThe Hilbert–Huang transform ( HHT) is a way to decompose a signal into so-called intrinsic mode functions (IMF) along with a trend, and obtain instantaneous frequency data. It is …
