ElectroPuls is driven by a linear synchronous motor and requires additional highquality velocity feedback for precise dynamic control--due to the challenges of driving linear motors with lower inherent damping
than traditional rotary designs.
In all cases, the inherent damping of sailplane structure was neglected.
Reduced aerodynamic damping does not necessarily represent a flutter problem, because the inherent damping of sailplane structure was neglected at current stage of investigation and the aerodynamic models used in analyses were not validated.
Shaft length is critical for rotor dynamics," explains Barrett, "especially as we use air bearings, which have little inherent damping
Many isolator materials such as elastomer-type isolators and pad-type isolators possess inherent damping, which should be considered when using this formula.
The large dynamic displacement attenuates vibration, while the inherent damping provided by the sliding friction between the strands of the wire rope minimize post-shock noise and lower resonant peaks.
The steel frame estimated inherent damping
of 1% meant unacceptable lateral accelerations.
The inherent damping
effect of the WinDrive hydro-dynamic system reduces the mechanical shocks experienced during "low voltage ride through" and is based on the reliable Vorecon technology of Voith AG, a hydro-dynamically adjustable drive that has been extensively used in the gas turbine industry for many years.
This presentation deals with the elasticity and strength of rubber, its viscoelastic properties that cause rubber to have inherent damping
, and the laboratory measurement and interpretation of tear strength, fatigue resistance and adhesion to wire cord.
Elastomers have been widely used in many areas of technology for achieving acoustic and vibration isolation and damping owing to a unique combination of low modulus and inherent damping
The inherent damping
qualities of the design make the units suitable for vertical applications requiring either noise or vibration control, and the load transfer method ensures torque consistency and repeatability in either direction.
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 systems.
