Hello, this si Collins and am a MatLab expert.
Having gone through your project I understand that you need a rolling element bearing fault diagnosis done on matlab and the above can be solved using the wavelet transform function.
Localized faults in a rolling element bearing may occur in the outer race, the inner race, the cage, or a rolling element. High frequency resonances between the bearing and the response transducer are excited when the rolling elements strike a local fault on the outer or inner race, or a fault on a rolling element strikes the outer or inner race.
Please get in touch for further discussion.
