Abstract
A vibration damping device equipped with a resonator mechanism comprising at least one resonator, the at least one resonator having a first beater extending from an embedded end to a free beating end. The resonator consists of an elastically deformable base equipped with a first branch and a second branch connected by a central section, the embedded end being embedded at the first branch, the first branch extending from a first end to a second end each rigidly fastened to a mount, the second branch extending from a first end section to a second end section each rigidly fastened to a vibration source.
Claims20
A vibration damping device comprising:
- a resonator mechanism including at least one resonator, the at least one resonator including at least one beater having a first beater extending from an embedded end to a beating free end, the at least one resonator further including an elastically deformable base,
- wherein the base includes a first branch, a second branch, and a central section, the embedded end being embedded in the first branch, the first branch extending from a first end to an intermediate portion to a second end, each of the first end and the second end being rigidly fastenable to a mount, the second branch extending from a first end section to an intermediate section to a second end section, each of the first end section and the second end section being rigidly fastenable to a vibration source, the first branch and the second branch being connected together by the central section being directly connected between the intermediate portion of the first branch and the intermediate section of the second branch with none of the ends of the first branch being directly connected to any of the end sections of the second branch.
A vibration damping device for mitigating vibrations emitted by a vibration source to limit transmission of the vibrations to a mount that is spaced apart from the vibration source along a vertical axis, the vibration damping device comprising:
- a resonator mechanism having a resonator, the resonator including a first beater extending from an embedded end to a beating free end;
- and
- the resonator further including an elastically deformable base having a first branch, a second branch, and a central section, the embedded end being embedded in the first branch, the first branch extending from a first end to an intermediate portion to a second end, each of the first end and the second end being rigidly fastened to the mount, the second branch extending from a first end section to an intermediate section to a second end section, each of the first end section and the second end section being rigidly fastened to the vibration source, the first branch and the second branch being connected together by the central section being directly connected between the intermediate portion of the first branch and the intermediate section of the second branch with none of the ends of the first branch being directly connected to any of the end sections of the second branch.
A vibration damping device for mitigating vibrations emitted by a vibration source to limit transmission of the vibrations to a mount that is spaced apart from the vibration source along a vertical axis, the vibration damping device comprising:
- a resonator mechanism arranged at an interface between the mount and the vibration source, the resonator mechanism having a resonator including a first beater extending from an embedded end to a beating free end;
- the resonator further including an elastically deformable base having a first branch and a second branch connected by a central section, the base including the first branch, the second branch, and the central section being arranged on a plane normal to the vertical axis, the embedded end being embedded in the first branch, the first branch extending from a first end to an intermediate portion to a second end, each of the first end and the second end being rigidly fastened to the mount, the second branch extending from a first end section to an intermediate section to a second end section, each of the first end section and the second end section being rigidly fastened to the vibration source.
