Produktbeschreibung
Random Vibration in Spacecraft Structures Design is based on the lecture notes "Spacecraft structures" and "Special topics concerning vibration in spacecraft structures" from courses given at Delft University of Technology. The monograph, which deals with low and high frequency mechanical, acoustic random vibrations is of interest to graduate students and engineers working in aerospace engineering, particularly in spacecraft and launch vehicle structures design. This book treats the random mechanical and acoustical vibrations of deterministic and statistical dynamic systems, in the low and high frequency range. The following topics are discussed in great detail:
Vibrations of deterministic linear mechanical dynamic systems exposed to mechanical random loads and or enforced motion (acceleration); Vibrations of deterministic linear mechanical dynamic systems exposed to random acoustic loads (sound pressures; Random vibration of statistically defined mechanical systems and loads using Statistical Energy Analysis (SEA); Non-linear structures excited to random (white noise) mechanical loads analyzed by using the Fokker-Planck-Kolgomorov (FPK) equation.
The theory of random vibration is strongly related to the design of spacecraft structures and is illustrated with simple and more difficult worked examples; each section ends with posed problems; usually answers are provided.

Rezensionen
From the reviews:

"This text provides an excellent introduction to the wide range of topics required in vibration and acoustic engineering. ... It allows the working engineer to get good in depth coverage of the features without the excessive details other texts have. I recommend this book for the practicing engineer as well as students, it meets its purpose of providing the theory as well as practical applications for mechanical and acoustics vibrations of dynamic systems and how that applies to spacecraft design engineering." (Timothy J. Copeland, Noise Control Engineering Journal, Vol. 58 (5), September-October, 2010)

"The book is based on the author's lecture notes to the graduate students at The Delft University of Technology and his practical experience gained at Dutch Space BV ... . The material presented in this book could not be found in its entirety, or even in some parts, in any other references. It is extremely valuable to practicing aerospace engineers to find it collected and clearly presented in one volume. ... a highly recommended book for industry practitioners and graduate students in aerospace engineering." (Haisam Osman, International Journal of Acoustics and Vibration, Vol. 16 (3), 2011)
