| Abstract: | The main idea of Hilbert-Huang transform is to separate the analyzed signals into components with different time scale,using the empirical mode decomposition.Then the Hilbert transform is applied to each intrinsic mode function.Therefore,the time-frequency distribution is obtained.The basic method is introduced in detail.The energy spectrum is applied in the research of the faults diagnosis of roller bearing.Firstly, the analyzed signals are separated into a series of intrinsic mode function using the empirical mode decomposition.Then,the energy spectrum is applied to the intrinsic mode function.The experimental results show that this method based on Hilbert-Huang transform and energy spectrum can effectively diagnose the faults of roller bearing. |
