Rotordynamics are of great importance in the design,
manufacture and assembly of turbomachines as well as in
ensuring their safe operation. Also important are the
dynamics of the foundation and its interaction with the
dynamics of the rotor.
This book is divided into four parts. Following a
presentation of the basic theory the dynamics of rotors
supported on several bearings. The third part describes the
dynamics of foundations of turbine line-outs and the
calculations for a turbomachine coupled with its foundation.
The last part includes a section on estimation procedures, a
comprehensive presentation of the theoryand practice of
rotors having a transverse crack, a section on the
mathematical fundamentals and a description of the computer
program used for the examples in the book.
The book addresses both the practical engineer and the
theoretician and should provide manufacturers, operators,
university and polytechnic lecturers and students with an
understanding of the vibrations of turbomachines. The
results are described in such a way that they can be easily
understood and applied.
