Abstract EN
Rolling element bearing is a very important part of mechanical equipment and widely used in rotating machinery.
Rolling element bearings could appear localized defects during the working condition, which would cause the complex vibration response of bearings.
Considering the shaft and bearing pedestal, a 4 degree-of-freedom (DOF) dynamic model of rolling bearing with compound localized fault is established based on time-varying displacement, and the vibration characteristics of rolling bearing with localized faults under different conditions are investigated.
The established model is verified by the experimental vibration signals in time domain and frequency domain.
The results show that the vibration response of compound fault is the result of the coupling action of a single fault of rolling element and outer race.
The influences of compound fault on the vibration signals of the bearing were analyzed under three conditions.
With the increasing of radial load, defect size, and rotation speed, the vibration amplitude of bearing would increase correspondently, which would accelerate the failure rate of bearing and reduce the service life of bearing.
This model is helpful to analyze the vibration response of the rolling element bearing with single or compound fault.
