Abstract
The present disclosure relates to a frequency tuned damper having a vibration body (19) and at least one elastic element (11, 13, 15, 17) which connects the vibration body to a surface (21), the vibrations of which is to be dampened. The elastic element has a wide portion (29) and a narrow portion (31) disposed at different locations on an axis (39) which is substantially parallel with the normal of the surface. The wider portion has a cavity (41), and the wide and narrow portions are inter-connected by a transition portion (43). The part of the narrow portion that is closest to the transition portion fits inside the cavity, as seen in the direction of the axis, such that the narrow portion can be pushed at least partly into the cavity, thereby flexing the transition portion.
Claims20
A frequency tuned damper having a vibration body and at least one elastic element which is adapted to connect the vibration body to a surface, the vibrations of which is to be dampened, the elastic element having a wide portion and a narrow portion disposed at different locations along a longitudinal axis which is substantially parallel with the normal of the surface when the damper is mounted, one of said portions being adapted to attach the elastic element to the vibration body and the other to attach the elastic element to the surface, the wider portion having a cavity, characterized in that
- the wide and narrow portions are inter-connected by a transition portion, and
- in that the part of the narrow portion that is closest to the transition portion fits inside the cavity, at the part thereof that is located in the wide portion closest to the transition portion, as seen in the direction of the longitudinal axis, such that the narrow portion can be pushed at least partly into the cavity, thereby flexing the transition portion.
