| Abstract: | In this paper,the MISEP is mainly made use of separating helicopter gearbox signals in the non-linear mixture.The MISEP can separate the bearing vibration signal effectively from other source signals.As the method applying to the actual aero-engine vibration signal analysis,the method can separate actual chaotic vibration signal from the actual aero-engine vibration signals too.The results show that the MISEP was an effective signal processing method in mechanical faults diagnosis domain. |
