Abstract
A resonator having a support and a seismic mass. Movement means include a first electromagnetic assembly comprising a first electric coil that is not electrically powered. An actuator is connected to a processor unit, the processor unit electrically powering the actuator with adjustable electrical power. A resilient member is interposed between said seismic mass and said support.
Claims23
A resonator for countering vibration of a carrier structure, the resonator being provided with a seismic mass and a support for fastening to the carrier structure, the resonator including movement means connecting the seismic mass to the support while allowing the seismic mass to perform oscillating movement relative to the support, wherein the movement means comprise:
- a first electromagnetic assembly comprising one element secured to the seismic mass and another element secured to the support, one of the elements comprising a first electric coil and the other element comprising a first permanent magnet, the first electric coil not being electrically powered;
- an electric actuator for acting on a movement of the seismic mass relative to the support, the actuator being connected to a processor unit, the processor unit being configured to power the actuator electrically in variable manner determined as a function firstly of a relative movement between the carrier structure and the seismic mass, and secondly of an individual movement of the carrier structure;
- and
- a resilient member interposed between the seismic mass and the support.
A method of countering vibration of a carrier structure by means of a resonator, the resonator being provided with a seismic mass and a support for fastening to the carrier structure, the resonator including movement means connecting the seismic mass to the support while allowing the seismic mass to perform oscillating movement relative to the support, wherein the movement means comprise:
- a first electromagnetic assembly comprising one element secured to the seismic mass and another element secured to the support, one of the elements comprising a first electric coil and the other element comprising a first permanent magnet, the first electric coil not being electrically powered;
- an electric actuator for acting on a movement of the seismic mass relative to the support, the actuator being connected to a processor unit, the processor unit being configured to power the actuator electrically in variable manner determined as a function firstly of a relative movement between the carrier structure and the seismic mass, and secondly of an individual movement of the carrier structure;
- and
- a resilient member interposed between the seismic mass and the support, the method comprising a step of electrically powering the actuator with variable electrical power determined as a function firstly of the relative movement between the carrier structure and the seismic mass, and secondly of the individual movement of the carrier structure.
A resonator for countering vibration of a carrier structure, the resonator being provided with a seismic mass and a support fastenable to the carrier structure, the resonator including a movement assembly connecting the seismic mass to the support while allowing the seismic mass to perform oscillating movement relative to the support, wherein the movement assembly comprising:
