The development of the satellite structure necessitates a good understanding of the static and dynamic characteristics of the satellite to establish design and test loads. Static strength verification is accomplished by a static-centrifugal test. Static tests objective is verification of strength of the satellite structure in accordance with accepted types of loading and determination of load-carrying ability of the structure. Dynamic tests objectives are the estimation of the vibration-transfer coefficients to the mounting seats of the satellite‘s components, modal frequencies of the satellite structure components and satellite structure as a whole, effect of the impact loads on satellite’s equipments mounting accuracy, and verify the electrical equipments function due to vibrations. The full list of qualification tests is discussed in this chapter. Then, finite element method is used to investigate cracks that were initiated during air transportation vibration test of satellite structure strength mockup.
