The Empirical Mode Decomposition ( EMD) package contains Python (>=3.5) functions for analysis of non-linear and non-stationary oscillatory time series. EMD implements a family of sifting algorithms, instantaneous frequency transformations, power spectrum construction and single-cycle feature analysis.

WebOct 5, 2024 · In this study, horizontal vibration acceleration signals from ball bearings are utilized to extract the health indicator by Hilbert–Huang entropy. This indicator is the input to the linear degradation model. If the indicator reaches the degradation detection threshold, its RUL is predicted using this model. 2. 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 designed to work well for data that is nonstationary and nonlinear.
