Abstract: The satellite encounters a vibro-acoustic environment in the powered phase caused by the pulsating and the thrust of the engine and the aerodynamic noise. The random vibration test, the acoustic noise test and the vibro-acoustic test are carried out separately for a satellite model. By comparing these results, it is found that at different frequency ranges, the base vibration and the acoustic noise have different effects on the structure's vibro-acoustic response. Based on this, a method is proposed to predict the vibro-acoustic response using the sum or the extremum envelope of the vibration and noise responses.
