Abstract
(EN)
A tuning element that can be integrally formed with a resilient body of a bush and configured to reduce dynamic stiffness increases associated with eigenmodes of the resilient body within a predetermined operational vibration frequency range. The tuning element may resemble an upstanding wall or wing on an outer surface of the resilient body. The resilient body may comprise a plurality of radial arms having axial passageways therebetween. The tuning element may bridge the passageways. A bush configured in this way may be particular suitable for use in scenario where the operational vibration frequency range comprises high frequency, such as an engine mount for an electric vehicle.

L'invention concerne un élément d'accord qui peut être formé de façon intégrée avec un corps élastique d'une douille et configuré pour réduire des augmentations de raideur dynamique associées à des modes propres du corps élastique à l'intérieur d'une plage opérationnelle prédéterminée de fréquences de vibrations. L'élément d'accord peut ressembler à une paroi ou à une aile dressée sur une surface extérieure du corps élastique. Le corps élastique peut comporter une pluralité de bras radiaux entre lesquels se situent des passages axiaux. L'élément d'accord peut enjamber les passages. Une douille ainsi configurée peut convenir tout particulièrement à une utilisation dans un scénario où la plage opérationnelle de fréquences de vibrations comprend une fréquence élevée, comme un support de moteur destiné à un véhicule électrique.
