Abstract : The previous report ASD TDR 63 205, (AD-405 919) and the present one study two main areas: the replacement of acoustic excitation by direct mechanical excitation and the response of substructures tied to a randomly vibrating primary structure. This report presents techniques of measurement of power flow from a shaker to a structure, a detail analysis of the case of edge connections, the results of mechanical simulation of an acoustic test applied to a model electronic package, and a discussion of acoustic and vibration tests performed on an Atlas Guidance Computer.
