Fault Diagnosis of Variable Speed Gear based on ATF and ASAD
Aiming at the problem that is difficult to extract the fault features of gears under variable working and strong noise conditions，a fault diagnosis method based on adaptive time-varying filtering（ATF） and angle domain synchronous average（ASAD） is proposed. By combining ASAD and ATF，the signal after...

| description | Aiming at the problem that is difficult to extract the fault features of gears under variable working and strong noise conditions，a fault diagnosis method based on adaptive time-varying filtering（ATF） and angle domain synchronous average（ASAD） is proposed. By combining ASAD and ATF，the signal after noise reduction is analyzed by order spectrum，and the local fault of gear can be diagnosed by modulation side frequency band in order spectrum. The simulation data and the data analysis of the variable speed gearbox test bench show that the proposed method has a good signal analysis adaptability for the gear vibration signals under the variable speed condition，and can not only filter out noise interference well，improve the noise suppression effect in the pass band，but also effectively highlight the gear fault characteristics under the variable speed condition. |
