The rolling bearing rotor (RBR) system is the kernel of many rotating machines, which affects
the performance of the whole machine. Over the past decades, extensive research work has …

Rolling element bearings (REBs) play a most critical role in various industrial machinery. A
clearly and in-depth understanding of vibration characteristics of REBs is very helpful for …

From a kinematic point of view, rolling elements should continuously roll on the raceways of
rolling element bearings. When the dynamic behaviour is also considered, pure rolling …

This paper provides insights into the physical mechanism by which defect-related impulsive
forces, and consequently, vibrations are generated in defective rolling element bearings. A …

This paper presents an improved nonlinear dynamic model of the contact forces and
vibration response generated in defective rolling element bearings. The improvement comes …

This paper presents a review of literature concerned with the vibration modelling of rolling
element bearings that have localised and extended defects. An overview is provided of …

The occurrence of skidding and overskidding behaviour is likely to scratch rolling element
raceways and lead to a significant temperature rise and thermal deformation. The ball-cage …

In current bearing dynamic models, the displacement coordinate relations are usually
utilized to approximately obtain the contact deformations between the rolling element and …

The traction motor is the power source of the locomotive. If the surface waviness occurs on
the races of the motor bearing, it will cause abnormal vibration and noise, accelerate fatigue …

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) …
