Vibrations of Spalled Rolling Element Bearings

Rolling element bearings are at the heart of almost
every rotating machine. They have received a lot of
attention in the field of vibration analysis as they
represent a common source of faults, which can be
detected at an early stage. This book provides an
insight into the vibrations of defective rolling
element bearings with the aim of improving their
reliability, developing state of the art vibration
analysis algorithms and improving the understanding
of the interactions between bearings and gears. The
book touches on the three main areas, which are
relevant to the condition monitoring of rolling
element bearings. These are diagnostics, prognostics
and fault simulation. A novel signal-processing
algorithm to diagnose localized faults in rolling
element bearings has been developed. The problem of
modelling the vibration signals from a spalled
bearing in a gearbox environment has been discussed.
The book is written for researchers, academics,
reliability and maintenance engineers who work in the
filed of machine condition health usage and
monitoring and have an interest in vibration signal
processing, dynamic fault simulations, fault
detection, and remaining useful life prognosis
