The device comprises at least three isolating modules (11) each having two rigid pieces (12, 15), one (12) of which is fastened to the carrier structure (14) and the other (15) of which is fastened to the support (17) for the vibrating equipment, these pieces (12, 15) being linked by at least one isolating stud (18) made of an elastomer, which attenuates the transmission of low-amplitude vibrations from the equipment to the structure (14), the deformation of at least one stud (18) in tension-compression and in shear being limited by three flexible stops (19a, 19b) each mounted on only one of the pieces (12, 15) and the free end of which is facing the other of said pieces (15, 12) and not in contact with it, at rest. Each stop (19) comprises an elastomer element coming into contact with the facing other piece (15, 12) during deformations of sufficient amplitude of the isolating stud (18), the stiffness of the elastomer of the stop (19) being greater than that of the stud (18). Application to the isolation of vibrating equipment on a satellite carrier structure. |
