Abstract : Three methods of measuring mechanical impedance in missile structures are discussed: (1) application of a sinusoidal force, (2) application of an impulse, and (3) application of a random force. Equations which may be used to estimate the magnitude of response vibrations are presented. The effects of text fixtures, sinusoidal sweep rates, and other special problems associated with each of the methods are also discussed. In the concluding pages, the advantages and drawbacks of each of the methods are compared. (Author)
