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 approach simple and possible to analysis the each panel instead of mounted on satellite. We found that it doesn't need to test and calculate the full configuration, as the conclusion, the predicton method may be simplified to treat the panel alone. And more, we can propose the simplified method by the impedance coupling approach based on SEA to predict random acoustic vibration response with mounted equipments on honeycomb panel, which is the common satellite. It can be given good results.
