Dynamic vibration absorber

The Journal of the Acoustical Society of America, 1979
This invention relates to suppression of vibrations in massive systems including large rotating elements such as induction fan rotors used in electric power generating plants. In particular, this invention relates to the provision of a tuned vibration absorber with very low damping, often known as a dynamic vibration absorber, which acts to reduce or ...

The Theory of the Dynamic Vibration Absorber

Transactions of the American Society of Mechanical Engineers, 1928
Abstract The “vibration absorber” discussed in this paper consists of a small vibratory system tuned to the operating frequency of a larger machine and attached to it in a suitable location. When properly designed this will reduce the vibrations of the machine itself materially.

The broadband dynamic vibration absorber

Journal of Sound and Vibration, 1982
The limited effectiveness of the linear passive dynamic vibration absorber is described. This is followed by an analysis producing the response of a primary system when a non-linear softening Belleville spring is used in the absorber. It is shown that the suppression bandwidth can be doubled by this means.

The cruciform dynamic vibration absorber

The Journal of the Acoustical Society of America, 1984
The cruciform dynamic absorber comprises two free–free beams that are mass loaded at their free ends and that are joined centrally at right angles at a point at which they are attached to the vibrating item or structure of concern. Both a lumped simple system and distributed mechanical systems such as beams and clamped circular plates are considered ...

A Thermoviscoelastic Dynamic Vibration Absorber

Journal of Applied Mechanics, 1998
A dynamic vibration absorber with a viscoelastic element is studied. The viscoelastic element is modeled as a material with memory in which the internal dissipative force depends on current, as well as previous deformations. The viscoelastic behavior is governed by two parameters: the relaxation modulus Go, and the relaxation time γ.

Dynamic vibration absorber

The Journal of the Acoustical Society of America, 1988
A vibration damping arrangement for a structural member including leaf springs extending horizontally from a vibration absorber body adapted to be attached to the structural member. A set of horizontal-vibration-absorbing leaf springs extends in one horizontal plane while a set of vertical-vibration-absorbing leaf springs extends in another horizontal ...

Damped dynamic vibration absorber

The Journal of the Acoustical Society of America, 1986
A pump is disclosed having a damped dynamic vibration absorber for attenuating pump vibration in response to a periodic disturbing force generated when the pump is in operation. The vibration absorber comprises elastic means, an annular mass and an energy dissipative means.
