| Abstract: | The wavelet analysis has the good time-frequency analysis characteristic.If the technology of wavelet analysis is applied to analyze and process the mechanic vibration signal,it can correctly recognize the mechanic running state,make up for the traditional analysis and carry out mechanic state inspection.A system for state inspection and fault diagnosis has been designed,and the system feasibility and practicability have been validated by example. |
| Keywords: | hydraulic generating sets state inspection fault diagnosis wavelet analysis |
