This paper deals with a method for determining a vibration isolation system capable of attenuating airborne induced vibration imparted to the stable crystal oscillators used in airborne radars. Suitable isolation is achieved when maximum permissible vibration levels, based on system noise limits, have not been exceeded. Included in this paper is a procedure for calculating the response of multi-stage (or single stage) vibration isolation system. Foremost, the procedure considers the 'real world' effects introduced by complex, nonhomogeneous structures. Essentially, the approach depends on assuming a reasonable value for the occurrence of the first major structural resonance (not the isolators) and the ensuing selection of a damping ratio.
