FIELD: mechanics.
SUBSTANCE: invention relates to devices designed to reduce vibration and shock effects, and may be used in designing anti-vibration and anti-shock protection of whatever engineering systems and structures. The damper incorporates a rod, damping elements and plates. The rod is a multi-layer design, the layers featuring different acoustic susceptibility. Every layer is fabricated as a thin-wall cylinder supported by a leg and having a thread made on the cylinder inner surface and the leg outer surface. The damper is provided with tight casing filled with a liquid and fitted on the rod. The damping elements are made in the form of split plates forming the petals, every petal featuring a different intrinsic frequency of elastic oscillations. Higher rigidity of coupling is provided.
EFFECT: higher rigidity of couplings.
