Abstract
A device for providing a rigid mechanical link with frequency cut-off between two structures, the device comprising a rigid tie-rod (14) the ends of which are secured to the two structures (10, 12) and a cylinder and piston assembly (16, 18) in parallel with the tie-rod (14), the two ends of the cylinder (16) being interconnected by a duct (22) which, together with the cylinder (16), is filled with a liquid of very low viscosity, the device providing filtering of a low excitation frequency applied to one of the structures and preventing the transmission of this frequency to other structures.
