A novel method is proposed for quantitative and localization diagnosis of a bearing outer
ring defect in this paper. This method aims to distinguish these defects with different angular …

Vibrations of a roller bearing (RB) with a localized defect (LOD) are determined by LOD
edge shapes, which can be used to detect and diagnose the LODs. Therefore, it is very …

The better understanding of the vibration characteristics of a bearing with defects is crucial
for the fault diagnosis of rolling element bearings (REBs). In the current paper, the vibration …

Ball passing frequencies (BPFs) are very important features for condition monitoring and
fault diagnosis of rolling ball bearings. The ball passing frequency on outer raceway (BPFO) …

The accuracy of the vibration response simulated by the dynamic model of the defective
bearing depends on the precise expression of the interaction between the rolling elements …

Accurately establishing a dynamic model of rolling bearings is significant for understanding
the fault mechanism and analyzing the motion characteristics under different performance …
