Validation of LACE Spacecraft Vibroacoustic Prediction Model

The purpose of this article is threefold:

• To verify that the VibroAcoustic Payload Environment Prediction System (VAPEPS), as developed by the Lockheed Missile and Space Company and monitored by the Jet Propulsion Laboratory (JPL), is a viable means of predicting spacecraft component responses to an acoustic environment.

• To address the determination of important parameters in the creation of a Statistical Energy Model in order to achieve accurate results using VAPEPS.

• To present a technique for deriving component random vibration test levels from these results.
