This book is for designers, partition engineers, and student of engineering. It introduces
the fundamental knowledge used in mechanical vibrations. This knowledge
can be utilized to develop computer programs for analyzing, designing, and optimization
of vibration problems in industrial systems.
Vibrations have been in the engineering curriculum for around a hundred years.
Many good books on the subject are available. The 1896 Lord Rayleigh’s “Theory
of Sound” is the first modern book on the subject of sound, wave propagation, and
vibrations. However, the first books on vibrations with a mechanical engineering
viewpoint appeared as “Vibration Problems in Engineering” (1928) by the father
of modern engineering mechanics, Stephen P. Timoshenko, and then as “Mechanical
Vibrations” (1934) by J.P. Den Hartog. Although Timoshenko was the architect
of modern structure of engineering education and his various books were used
for a long time in educating mechanical and civil engineers, it was Den Hartog’s
Mechanical Vibrations that globally was accepted as a classical educational book.
Almost all mechanical vibration books that appeared after 1940 follow the structure
of Den Hartog’s, starting with time response and ending with frequency response.
Sometimes a glance at random vibrations, nonlinear vibrations, continuous
systems, vibrations control, or modal analysis may also be seen in various books.
On the contrary, the present book begins with frequency response and continues by
time response and ends with optimization and application, focusing only on discrete
mechanical systems. Starting with frequency and steady-state response of vibrating
systems is more practical and more fundamental than time and transient response. |
