Statistical Energy Analysis of Vibration Transmission into an Instrument Package

Random vibration transmission from a vibrating source into an instrument package is analyzed using statistical energy analysis techniques. A general outline of these techniques, followed by a specific application to an instrument box attached to a vibrating plate, is presented. Consideration is also given to vibration isolation of the instrument box and to a novel method of performing vibration tests of small instrument packages and components. The experimental results presented agree well with theoretical results and indicate that these new analysis techniques offer new insight into practical high-frequency vibration problems.
