Abstract: The vibro-acoustic test technology for satellites is studied, including the controlling method of the vibro-acoustic test and the test conditions of the random vibration-acoustic test by using the satellite board with a large area to mass ratio. The results show that the sine vibration control should be filtered and conducted before the acoustic control in the sine vibration-acoustic test; the influences of the acoustic excitation and the random vibration excitation are small and the excitation condition can be applied as is normal in the random vibration-acoustic test; the random vibration excitation and the acoustic excitation can be applied on the structure at the same time for the satellite with a large area to mass ratio in the vibo-acoustic test.
