Abstract
Provided is a tuned mass damper having multiple degrees of freedom installed in a device that generates vibrations to reduce vibrations and noise. For a rotating machine or other object that generates resonance during operation, the vibration and natural frequency of the object are measured before shipment, and a tuned mass damper having multiple degrees of freedom is designed and installed to target frequencies (operating frequency and multiple resonant frequencies) at which high vibrations are induced, thereby obtaining the effect of reducing vibrations and noise.
Claims11
A tuned mass damper having multiple degrees of freedom, comprising:
- a base plate;
- a plurality of first dampers provided on an upper surface of the base plate;
- a first weight plate mounted on upper portions of the plurality of first dampers;
- a plurality of second dampers provided on an upper surface of the first weight plate;
- a second weight plate mounted on upper portions of the plurality of second dampers;
- a plurality of first elastic members penetrating through the first weight plate and connecting the upper surface of the base plate and a lower surface of the second weight plate;
- at least one second elastic member provided between the base plate and the first weight plate;
- and
- a plurality of supports provided on a side surface of the base plate to be connected to at least the base plate among the base plate, the first weight plate, and the second weight plate.
