Natural Frequencies, an Approximation,Natural frequencies of spacecraft play a very important role in the design of spacecraft structures. In this chapter approximate methods the calculate natural frequencies, static displacement method, Rayleigh’s quotient and Dunkerley’s equation are presented and illustrated by examples.
