Abstract:
This paper discusses several techniques for supporting and exciting dynamic models of space vehicle structures to study their dynamic properties such as natural frequencies, mode shapes, damping, and response. Particular attention is given to a unique support harness for vertical support of missile-like structures with minimum lateral restraint. Included in the discussion of vibration exciters is an air shaker which is particularly useful for excitation of the natural modes of light structures and those having thin skins such as encountered on dynamic models of space vehicles.
