Random-Sine Vibration Equivalence Tests on Missile Electronic Equipment

摘要

Random-sine vibration equivalence data has been obtained through measurements of the structural dynamics of typical missile electronic equipment packages. Response data obtained was processed by extending the application of an existing single resonator theory for sine-random equivalence to multi-resonant systems. This extension of the theory is based on the assumption that negligible interaction occurs between significant resonances. This for the most part proved justified by the data. (Author)
