In the rotor-bearing system (RBS), the vibration interaction between the supporting bearings
can lead to a vibration response on a healthy bearing that resembles that of a faulty …

A cylindrical roller bearing (CRB) dynamic model including the race defects is developed for
use in estimating cage slip and roller-cage impact force (IF) for the given defect cases. The …

In order to realize high-precision diagnosis of bearings faults in a multi-sensor detection
environment, a fault diagnosis method based on two-stage signal fusion and deep multi …

Cage speed measurement has been extensively studied for the testing of aerospace
bearing; however, existing cage-speed measurement methods have limitations such as …

The vibration response of ball bearing with local defect is closely associated with its
lubrication condition. The previous bearing dynamic models were mainly established based …

The bearing slip ratio is an effective index for bearing slip evaluation, and is also of great
significance for bearing design and condition monitoring. In this paper, we proposed a slip …

To illustrate the vibration characteristics of the defective bearing more precisely, a dynamic
model considering the detailed motion of the roller and the impact between the roller and the …

The fault diagnosis of rolling bearings is very important in industrial applications, which can
avoid accidents and reduce operation and maintenance costs. Although the position of the …

The quantitative diagnosis of rolling bearing defects still mainly relies on the manual
analysis of vibration signals and is limited to a specific moment in time, which restricts the …

Slipping and local defects are significant causes of abnormal vibration and instability in
rolling element bearings (REBs). In particular, the secondary slipping of rolling elements …
