Since the inherent damping
in structural metals is very low, it is necessary to increase the damping
of structures made from these materials by the use of appropriately designed damping
Using equation (2), coefficient of viscous damping
[kappa], in case of considered vibration of buckled beam, could be calculated as
Bi-State Real Time Damping
-- designed for up-level sport-utility vehicles as well as passenger car platforms, Bi-State Real Time Damping
is a semi- active, two position monotube damping
control system that automatically responds in real time to road and driving conditions based upon sensors that monitor vehicle motion and driver input.
MagneRide adjusts the damping
force at each corner of the vehicle in reaction to inputs from the road.
Alexandridis, who led the MagneRide development team, said the system revolutionizes Continuously Variable Real Time Damping
(CVRTD) suspension technology through use of innovative, Delphi-developed Magneto-rheological (MR) fluid and valve-less, monotube struts and shock absorbers.
Very light damping
greases are used, for example, to control the feel and sound of the "return" key on a computer keyboard; very heavy damping
greases would serve the same function in an automotive suspension system.
The results of these experiments, bending storage modulus (E') and damping
(tan delta), as functions of temperature, are shown in figure 5.
Further temperature-dependent measurements and characterization of films doped with different rare earths indicate that the increased damping
is due to local lattice distortions at the rare-earth sites due to anisotropic orbitals that are strongly coupled to the film magnetization.
ADL's recently established Center for Acoustical Technology is also actively involved in technology development for Lodengraf(TM) damping
, including the creation of new formulations for materials that will have interesting and novel properties.

The Smart Shock provides a radical performance improvement over conventional manually-adjusted shocks in which the rider pre-sets the comprehension damping
level between "soft" and "hard.
Dynamic mechanical analysis products from the company are said to offer unsurpassed measurement of modulus and damping
(tan delta) over broad temperatures, frequencies and environments.
Building on the award-winning piezoelectric damping
technology that made K2 the top selling alpine ski brand in the United States this year, K2 has developed a patented bike shock that brings a new generation of "smart" suspension technology to mountain biking.
Typical applications include sealants and adhesives, sound deadening and vibration damping
, polymer modification and membranes.
