Theoretical backgrounds of Miles' equation are kept simple and discussed using several approaches Contains many realistic (practical) examples Real specifications about random and acoustical vibrations are applied in the examples All random response analyses are made very clear and can be easily repeated by the reader Useful in solving problems in the frame of random vibrations in spacecraft structures design

Klappentext

This book discusses the theory, applicability and numerous examples of Miles' equation in detail. Random vibration is one of the main design drivers in the context of the design, development and verification of spacecraft structures, instruments, equipment, etc, and Miles' equation provides a valuable tool for solving random vibration problems. It allows mechanical engineers to make rapid preliminary random response predictions when the (complex) structure is exposed to mechanical and acoustical loads. The book includes appendices to support the theory and applications in the main chapters.
