Abstract |
|
Vibration problems in rotors can be extremely frustrating and may lead to greatly reduced reliability. rubbing is common faults in rotating machinery because of the clearance between the rotor and the stator. These problems cause malfunctions in rotating machinery and create strange vibrations coming from impact and friction. However, non-linear and non-stationary signals due to impact and friction are difficult to identify. Therefore, exact time and frequency information is needed for identifying these signals. For this purpose, a newly developed time- frequency analysis method, HHT (Hilbert-Huang Transform), is applied to the signals of partial Conventional signal processing methods such as FFT, and CWT were compared to verify the effectiveness of fault diagnosis using HHT. |
