EXTENDED STUDY system and subsystem responses due to the dynamic OF THE VIBROACOUSTIC BEHAVIOUR interaction of the spacecraft structure and the sound field in the payload compartment. OF THE ARTEMIS ANTENNA REFLECTOR The frequency range 20-500 Hz is particularly critical in Authors: D. VAUCHER de la CROIX1, J. CADIEUX1, terms of stresses and interface forces for sensitive C.
