- •
Different fluctuating profiles of speed are considered for fault diagnosis of gearbox.
- •
A novel approach of frequency domain averaging of warped IMFs is presented.
- •
Different faults like crack, chipped and missing tooth gears are tested.
- •
No reference signal generating device is need, i.e., Tacho-less arrangement.
