Ambient Vibration Monitoring 

In-operation vibration monitoring for complex mechanical structures
and rotating machines is of key importance in many industrial areas
such as aeronautics (wings and other structures subject to
strength), automobile (gearbox mounting with a sports car body),
rail transportation, power engineering (rotating machines, core and
pipes of nuclear power plants), and civil engineering (large
buildings subject to hurricanes or earthquakes, bridges, dams,
offshore structures). Tools for the detection and the diagnosis of
small changes in vibratory characteristics are particularly useful
to set up a preventive maintenance policy based on the actual
evolution of the state of the monitored machine or structure, as
opposed to systematic a priori planning.

Ambient Vibration Monitoring is the backbone of such structural
assessment monitoring and control. It provides the possibility to
gain useful data under ambient conditions for the assessment of
structures and components.

Written by a widely respected authority in this area, Ambient
Vibration Monitoring describes the current practice of ambient
vibration methodologies illustrated by a number of practical
examples. Designed to aid the practical engineer with their
understanding of the topic, it is the culmination of many years of
practical research and includes numerous ‘real world’
examples. It also provides information on applicable
solutions.

This book will enable not only practitioners (in civil,
mechanical and aerospace engineering), but also researchers and
students, to learn more about the theory and practical
applications of this subject.
