Abstract
A selectively tunable vibration absorber includes a support member having an outer surface, and a selectively tunable element mounted relative to the outer surface of the support member. The selectively tunable element is selectively adjustable to attenuate vibrations in a selected frequency range perceived by the support member in a selected direction. A mass is supported by the selectively tunable element.
Claims14
A selectively tunable vibration absorber comprising:
- a support member including an outer surface;
- a selectively tunable element mounted relative to the outer surface of the support member, the selectively tunable element being selectively adjustable to attenuate vibrations in a selected frequency range perceived by the support member in a selected direction, wherein the selectively tunable element includes a body having a substantially circular cross-section having a central void, a first tuning feature is formed in the body radially spaced from the central void in a first direction and a second tuning feature is formed in the body radially spaced from the central void in a second direction, the second direction being substantially opposite of the first direction;
- and
- a mass supported by the selectively tunable element.
