Elastic strut with an integrated hydro-mechanic resonator, in particilar for the suspension of a gear box on a rotorplane, and a suspension device comprising such an application

摘要

in the elastic sheet incorporating a resonator hydro mechanical mass spring system, of the type with hydraulic amplification of the displacement of the swinging mass (7).the mass spring mounted between two opposing hollow piston booster is a double face mounted sliding on two cylinders (6) coaxialement opposed in a closed chamber filled with a fluid (10) in an inner tubular element (1) arranged in an element necessary to e xterne (2) with which it defines, at each end, and a chamber (18) filled with liquid.which is the cylinder (6), the elements (1, 2) forming the body of the mobile coaxiau00adlement sheet one over the other and fixed to each end of the watertight and elastic bearings for u00e9lastomu00e8 re.
