Paper Abstract

A common method of reducing vibration levels in structures is to coat the surfaces of the structure with a layer of viscoelastic materials which dissipates the elastic strain energy induced by the dynamic loading. The passive damping material is placed in areas of high strain energy to extract as much energy as possible from the structure, but the exact location of the material can tend to be arbitrary. A more systematic approach is demonstrated which uses an evolutionary method which allows viscoelastic surface coatings to be gradually built up until the required damping is achieved. In this way the material can be placed in a more efficient manner, and it is proposed that this leads to a better damping performance.
