Abstract
The invention relates to a resonant device comprising a mass/spring system composed of a main mass comprising at least one main mass element, and of at least one spring element (3). The device is one which comprises at least one additional mass (10) comprising at least one additional mass element (102) and a coupling device (204) able to couple the additional mass (10) to the main mass (1) and to decouple it therefrom, so as to modify the tuning frequency of the device.
Claims14
A resonant device comprising
- a mass/spring system comprising a main mass having a main direction of oscillation and comprising at least one main mass element, and at least one spring element,
- at least one additional mass comprising at least one additional mass element, wherein the at least one additional mass is held in position by an elastic device which exhibits an elastic degree of freedom in a direction substantially parallel to said main direction of oscillation of the main mass, and
- a coupling device releasably coupling the at least one additional mass to the main mass, so as to modify the tuning frequency of the device.
A resonant device comprising
- a mass/spring system comprising a main mass having a main direction of oscillation and comprising at least one main mass element, and at least one spring element,
- at least one additional mass comprising at least one additional mass element, and
- at least one electromagnetic assembly releasably coupling the at least one additional mass to the main mass so as to modify the tuning frequency of the device by selectively coupling and decoupling said assembly,
- wherein each of said at least one electromagnetic assembly comprises a first complementary device comprising at least one magnetic mass coupled to said main mass and a second complementary device comprising at least one electromagnet coupled to said at least one additional mass, the at least one magnetic mass and at least one electromagnet being disposed facing one another in such a way that, when said at least one electromagnet is activated, said at least one magnetic mass is mechanically engaged, so that the main mass and said at least one additional mass are coupled,
- wherein the coupling between said magnetic mass and the main mass is produced by at least one flexible leaf.
