US 10,865,531 B2 · Device for damping vibrations in a cable, notably a cable stay

Abstract

The damping device comprises: a base comprising a through-orifice for receiving said cable, said through-orifice extending along at least a longitudinal axis, and at least one cylinder connected to said base and inclined with respect to said longitudinal axis at an angle other than 90°, and, for said cylinder, a complementary cylinder connected to said base and inclined with respect to said longitudinal axis at an angle other than 90°, the cylinder and the complementary cylinder being arranged on either side of a plane orthogonal to the longitudinal axis, the orthogonal plane containing a centre of the base, said centre being situated along the longitudinal axis.

Dependent claims

A damping device for damping vibrations of a cable, the damping device comprising:

a base comprising a substantially cylindrical collar that delimits a passage orifice for reception of the cable, the passage orifice extending at least along a longitudinal axis;
at least one first piston damper connected to the base and inclined relative to the longitudinal axis by an angle not equal to 90°;
and
a second piston damper associated with the first piston damper, connected to the base and inclined relative to the longitudinal axis by an angle not equal to 90°,
the first and second piston dampers being located on opposite sides of a first plane orthogonal to the longitudinal axis and containing a centre of the base located along the longitudinal axis.
