A sound damping and vibration reducing material can quiet and reduce vibrations in electronic racks, chassis, enclosures and other products. Comprised of two or more metallic substrates surrounded by ...

In the last issue of MACHINE DESIGN, we examined methods to predict how vibration-isolation systems would perform. (“Shaking up vibration models,” Nov. 6, 2008, p. 63 to 68.) This discussion centered ...

Traditional isolators are built with metal springs or rubber blocks. They have low internal damping and generally are only effective at frequencies near 10 Hz. They also offer little to no isolation ...

The idea is simple: Protect sensitive objects from vibrating floors and foundations. So is the basic vibration-isolation system model, found in most every vibration textbook, and shown in the ...

SANDVIK COROMANT has upgraded the damping mechanism for its Silent Tools™ turning adaptors for more consistent performance and improved surface finish during internal turning operations at long ...

Traditional isolators are fabricated using metal springs or rubber blocks. They have low internal damping and only tend to be effective at frequencies in the region of 10 Hz. They also fail to isolate ...

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs ...

Controlling noise, vibration and harshness (NVH) is a critical part of quality assurance in consumer goods manufacturing. From cars and light trucks to washing machines, air-conditioners and pumps, ...

Materials researchers have created a new composite material that combines two incompatible properties: stiff yet with a high damping capacity. A compressor hums, an air conditioning system rattles, a ...
