342 Investigation about Prediction of Vibration of an Artificial Satellite by Sound Excitaton

Abstract

Payload and equipment mounted on honeycomb panels of artificial satellite are exposed to intense random vibro-acoustic environment during launch. In order to describe how payload components vibrate by the sound excitation along with certain margin regarding uncertainties in the early stage of design, this paper deals with the method to predict the random acoustic vibration of equipment mounted on honeycomb panel. This makes the prediction of local vibration possible to analysis by conbining Statistical Energy Analysis with Finite Element Method.
