In hard drives, for example, the damping
process is important for the write head that generates field pulses, the media that switch to record the field pulses as a magnetization pattern, and for the read head sensors that detect the fields from the recorded pattern.
The primary physical effects of damping
are that it limits the steady state motion of structures at their natural frequency and increases the rate of decay of vibration.
where C is viscous damping
, M is mass of the system, [omega] is vibration frequency and [LAMBDA] is logarithmic decrement.
We also continue to support the market with a full portfolio of damping
control and air spring technologies in order to provide OEMs the opportunity to achieve their desired ride characteristics, which is a critical touchpoint for consumers, on varying classes of vehicles.
There are multiple conflicting theories for damping
in metallic thin films.
Less costly "passive" adjustable units, on the other hand, rely upon grooves Formed in the shock's inner walls to alter the damping
The company's design utilizes a highly damped elastomer specifically formulated for the demanding requirements of helicopter main rotor damping
The broad frequency range and the angular control provided by this new spectrometer allows thorough testing of line width and damping
models that are needed to separate the inhomogeneous and intrinsic contributions to the measured resonance line width.
The MagneRide system -- introduced here at the Frankfurt International Motor Show (IAA '99) -- is a high-performance, high-value, semi-active suspension control system that optimizes vehicle ride and handling by providing Continuously Variable Real-Time Damping
(CV-RTD) control based on road and driver inputs.
For more than a decade, Nye's NyoGel 774 damping
greases have been used by manufacturers in many industries as an economical way to add a high-quality feel and sound to many low-shear devices, including microscopes, plastic molded switches, stereo tuners, and more than 30 automotive components -- all relatively low to moderate shear applications.
Modulus is calculated from the amplitudes of motion and force, while damping
is measured from the time delay (phase lag) from the applied force to the resulting motion.
They discovered that a few percent of Tb dopants in Ni-Fe films can dramatically increase the magnetic damping
without substantially changing the other magnetic properties.
