Viscous spring damper

The Journal of the Acoustical Society of America, 1986
A viscous spring damper including inner and outer members connected by an elastomeric shear spring and having a main or first fluid chamber disposed therebetween for communication with a second fluid chamber in the inner member through a restricted orifice.

Vibrations of a shallow cable with a viscous damper

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2001
Summary: We investigate the optimal tuning in terms of modal damping of a viscous damper mounted near the end of a shallow cable. The damping properties of free vibrations are extracted from the complex wavenumber. The full solution for lower modes is evaluated numerically, and an explicit analytical approximation is obtained.

A stay cable with viscous damper and tuned mass damper

Australian Journal of Structural Engineering, 2015
AbstractStay cables in cable-stayed bridges are vulnerable to dynamic excitation because their intrinsic damping is very low. The cables have often been exhibiting undesirable and excessive vibrations which result in increasing maintenance frequency and disruption to normal operations of the entire bridges.

Magnetic viscous damper

The Journal of the Acoustical Society of America, 1981
Disclosed herein is a rotary viscous damper using a magnetic fluid as the damping medium. The damper comprises a permanent magnet rotor enclosed in a magnetically permeable housing. The magnetic fluid fills the space between the rotor and the housing and is held in place using magnetic forces generated by the magnet rotor.

Viscous shear dampers

The Journal of the Acoustical Society of America, 1981
In a viscous shear damper the seismic mass is chamfered at all its corners. Thus, the clearances between the seismic mass and its casing are gaps with oppositely widening out sections separated by middle sections of smallest widths.

Rubber/viscous torsional vibration dampers

The Journal of the Acoustical Society of America, 1986
Tuned rubber/viscous torsional vibration damper assemblies of the kind having a supporting rotor disk mounting an inertia mass coupled to the disk by viscous damping medium and elastic tuning spring, spacing and sealing rubber rings located in rubber ring accommodating grooves. A viscous damping medium working chamber is defined within the inertia mass
