Vibration damping system and a method of damping vibrations
First Claim
1. A vibration damping system wherein the system comprises a magnetism generating medium and a magnetism energy dissipating medium whereby, in use, vibrations of the magnetism generating medium generate a magnetic field, the magnetism generating medium and the magnetism energy dissipating medium being so disposed with respect to each other that the magnetic field is then dissipated by the magnetism energy dissipating medium thereby damping the vibrations of the magnetism generating medium, the magnetism generating medium comprising a matrix and a plurality of magnetostrictive particles dispersed within the matrix and the magnetism energy dissipating medium comprises another matrix and a plurality of magnetostrictive particles dispersed within the said another matrix.

Abstract
A vibration damping system (8) wherein the system (8) comprises a magnetism generating medium (12) and a magnetism energy dissipating medium (16) whereby, in use, vibration of the magnetism generating medium (12) generates a magnetic field, the magnetism generating medium (12) and the magnetism energy dissipating medium (16) being so disposed with respect to each other that the magnetic field is then dissipated by the magnetism energy dissipating medium (16) thereby damping the vibrations of the magnetism generating medium (12).

27. A method of damping vibrations of a body wherein the method comprises the steps of:
-
(i) applying a magnetism generating medium to a body in the form of a coating that generates a magnetic field;
(ii) applying a magnetism energy dissipating medium to a secondary structure;
(iii) disposing the secondary structure in proximity to the body so that the magnetism generating coating and the magnetism energy dissipating medium are so disposed with respect to each other that the magnetic field is then dissipated by the magnetism energy dissipating medium thereby damping the vibrations of the body.
