Patent

CA 2416010

The invention concerns a vibration damping device comprising an element converting mechanical energy into electrical power mounted on a base designed to be fixed on a structure to be damped. Said converting element comprises an electrodynamic motor including a coil (20) mechanically connected to the base (1) and a magnetic circuit suspended by at least a spring (22), and the coil (20) is coupled with an electric charge having a resistive component and it includes a control device (COM) for varying the value of said resistive component based on at least two values.

L'invention concerne un dispositif d'amortissement de vibrations comprenant un dispositif de conversion d'énergie mécanique en énergie électrique monté sur une embase destinée à être fixée sur une structure à calmer. Ledit dispositif de conversion comporte un moteur électrodynamique ayant une bobine (20) reliée mécaniquement à l'embase (1) et un circuit magnétique suspendu par au moins un ressort (22), en ce que la bobine (20) est couplée à une charge électrique présentant une composante résistive et en ce qu'il présente un dispositif de commande (COM) pour faire varier la valeur de ladite composante résistive selon au moins deux valeurs.
