%X This paper presented a time-frequency signal processing method based on HHT for identification of nonlinear vibration systems.HHT used the current time scales that revealed by the signal's local maxima and minima to sequentially sift components of different time scales,starting from high-to low-frequency ones.On the other hand,because HHT did not use pre-determined basis functions and function orthogonality for component extraction,it provided more accurate time-varying amplitudes and frequencied of extract...
