Acoustical
and vibration isolation bearings are designed to eliminate noise and
vibrations, and have been used in structures such as railtrack systems,
concert halls and apartment buildings. Designed to support the load
of the structure, the dynamic properties of the elastomer are utilized
to achieve effective anti-vibration performance. A project that has
benifited from vibration isolation is:
The
Perelman Performing Arts Center at ground zero. |
