Monitoring vibrations in rotating machinery allows effective diagnostics, as abnormal
functioning states are related to specific patterns that can be extracted from vibration signals …

In order to study the vibration characteristics of inter-shaft bearing failures of a dual-rotor
system, an eight-degree-of-freedom dynamic model of dual-rotor system containing inter …

The lumped parameter modeling of a defective rolling element bearing involves the
evaluation of several quantities whose values are characterized by a high degree of …

Background Outer ring localized defects and inner ring misalignment are very common
failures in bearings, and they are likely to exist at the same time and have complex impacts …

Bearings often experience ring slip and raceway damage due to fit looseness, which
induces abnormal dynamic behavior. In this study, a dynamic model of the shaft-bearing …

Vibration signals are widely used in condition monitoring and fault diagnosis of high-speed
train axle box bearings (HSTABBs). However, there is a lack of mechanism research on the …

The dynamic parameters of high-speed train axle box bearing have time-varying
characteristics, it is necessary to investigate the influence of time-varying characteristics on …

A dynamic model for a ball bearing with an extended outer race defect has been proposed
in this paper with an aim of precise fault size estimation. Both the varying stiffness and …

In this study, the effects of the evolution of bearing outer race defect size and increase in
speed on the vibration characteristics of a shaft-bearing system under unbalanced …

The rotate vector (RV) reducer's needle roller bearings (NRBs) are vulnerable to wear and
flaws such as fatigue spalling of the raceway material. Studying the vibration mechanism …
