Paper Abstract

General rubber damping materials used in noise and vibrations attenuating system can not adapt large optical telescope's working temperatures and environments. While Metal Rubber material which has loose, reticulate structures can endure high or low temperatures, rigorous space environments, erosions, aging, volatilization and radiations due to its metallic properties because it is made of stainless steel wires of φ 0.1~0.3 mm. When the MR damping component is uploaded with vibrating force, the displacement will cause intense frictions between wires' surfaces which will dissipate abundant energy and thus it can serve as dampers like natural rubbers. Since Metal Rubber components are prepared by compression moulding, various complex shapes of dampers can be produced conveniently to fulfill large optical telescope's noise and vibrations attenuating tasks. Based on the Metal Rubber component's four preparation approaches, helix-making, planar roughcast-weaving, planar roughcast-rolling and 3D roughcast punching, a ring-shaped 3D parametrical numerical model is founded by CAD technology. Definitely, this modeling research work may support the optimization of the current trial and try preparation of MR component and it will provide necessary foundations for its further application in noise and vibrations attenuating system in large optical telescopes.
