Abstract
This document discloses a magnetic vibration dampener. The dampening device can be configured to attenuate movement of an object. The dampening device can include an electrically-conductive member, and a magnet. One of the electrically-conductive member and the magnet can be configured to be fixed to the object. The other of the electrically-conductive member and the magnet can be mounted for movement in relation to the electrically conductive member or the magnet fixed to the object. The electrically-conductive member can be positioned within a magnetic field of the magnet so that an eddy current generated within the electrically-conductive member by the magnet resists relative movement between the electrically-conductive member and the magnet.
Claims4
A dampening device comprising:
- a first magnet;
- a second magnet;
- a conductor;
- a first end cap;
- and
- a second end cap;
- wherein the first and second magnets are positioned relative to the conductor such that a force exerted on the device causes relative movement between 1) at least one of the first magnet and the second magnet and 2) the conductor;
- wherein the device is configured to dissipate the force at least in part through eddy currents generated in the conductor by the movement;
- wherein the first and second magnets are enclosed within the conductor,
- wherein the conductor comprises a first end that is fully enclosed by the first end cap and a second end that is fully enclosed by the second end cap, and
- wherein each of the magnets contained within the electrical conductor is isolated from direct mechanical contact from any other object other than the conductor, the first end cap, the second end cap, and any other magnets within the conductor.
