Hello everyone,

I am trying to generate a faulty acceleration signal with SIMULINK. The inner ring of the bearing is fixed to the shaft. The bearing has 17 rolling elements. I was thinking of creating a fault in the inner ring because it is attached to the shaft. My approach was to add 17 impulses per cycle to the original measured acceleration data in order to generate a faulty signal.

I attached a picture of my Simulink model. What do you think about this approach and is my model correct so far?

10.848 * f_wheel is the Ball Pass frequency of the inner ring.

Kind regards
