Abstract
The present disclosure relates to a damping system for counteracting oscillations in a construction. The damping system comprises a pendulum device and a container which contains a viscous medium. The pendulum device comprises a mass which comprises a porous structure. The porous structure is configured to allow the viscous medium to pass through it. The porous structure is at least partially submerged in the viscous medium.

A damping system for counteracting oscillations in a construction, the damping system comprising:
- a pendulum device;
- and
- a container containing a viscous medium;
- the pendulum device comprising a pendulum mass, the pendulum mass comprising a porous structure configured thereon;
- the porous structure is at least partially submerged in the viscous medium;
- the porous structure formed from an incompressible material selected from one of:
- steel, steel alloy, plastic material, ceramic material, or concrete;
- and
- the porous structure defining a baffle formed as a downward extending skirt on a lower-most portion of the pendulum mass, the baffle comprising passages defined completely therethrough such that movement of the pendulum mass back and forth from a neutral position causes flow of the viscous medium completely through the passages to induce vortices or turbulence in the viscous medium to dampen the oscillations.
A method for counteracting oscillations in a construction, comprising:
- providing a container with viscous fluid;
- mounting the container with viscous fluid inside the construction;
- suspending a pendulum mass having a porous structure configured thereon such that the porous structure is at least partially submerged in the viscous fluid;
- and
- wherein the porous structure includes a baffle formed as a downward extending skirt on a lower-most portion of the pendulum mass, the baffle comprising passages defined completely therethrough, the passages having a cross-sectional size and provided in a number such that movement of the pendulum mass back and forth from a neutral position causes flow of the viscous medium completely through the passages to induce vortices or turbulence in the viscous medium as the primary operational structure of the baffle to dampen the oscillations.
