Active Remote Dynamic Absorber

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">An active remote dynamic absorber (ARDA) is proposed for the vibration suppression of beams. The technique is an extension of the remote dynamic absorber method (RDA) that has been proposed recently. Both techniques (RDA and ARDA) are remote. That is, no direct attachment of the dynamic absorber beam to the primary

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 ...

Steering wheel dynamic absorber assembly

The Journal of the Acoustical Society of America, 2006
An assembly operable to be used with a steering wheel of a vehicle and to suppress a vibration transmitted to the steering wheel includes a plurality of support flexures and an inertial ring attached to the support flexures. The support flexures are operable to be attached to the steering wheel and the support flexures and the inertial ring are tuned ...

Synthesis of Dynamic Vibration Absorbers

Journal of Vibration and Acoustics, 1985
A method for designing dynamic vibration absorbers which create antiresonances at specified points on a sinusoidally forced vibratory system is described. Spring-mass absorber systems are treated in detail. Among all possible solutions, a unique minimum mass solution is shown to exist if the relative displacement of the absorber mass is constrained ...

Vibration absorber with dynamic damper

The Journal of the Acoustical Society of America, 2008
In an engine mount (A) whose axis (X) is oriented in the front to rear direction of a vehicle, a damper weight ( 12 ) is embedded within a toroidal stopper rubber ( 10 ) fixed at its inner periphery to the rear end of an inner cylinder ( 2 ). The damper weight ( 12 ) is made of, for example, steel plate to have a spiral form and placed to surround the ...

DYNAMIC ABSORBERS FOR AN EXTERNALLY EXCITED PENDULUM

Journal of Sound and Vibration, 2000
To an externally excited pendulum a dynamic absorber, which can move in transverse or longitudinal direction, is added. The quenching efficiency of two different systems is studied and compared. The absorber can be very efficient for slightly damped systems if it is correctly tuned. This is especially true when only small absorber mass can be adopted.

Dynamic absorber with pneumatic springs

The Journal of the Acoustical Society of America, 1980
The disclosure is directed to a dynamic absorber with pneumatic springs, which absorber is adapted for absorbing a vibration of a machine caused by an excitation force generated in the machine. The dynamic absorber comprises a pair of pneumatic springs disposed to be spaced apart from one another along a preselected spring action line, a weight means ...

Nonlinear Responses of Dual-Pendulum Dynamic Absorbers

Journal of Computational and Nonlinear Dynamics, 2009
The nonlinear responses of a single-degree-of-freedom system with two pendulum tuned mass dampers under horizontal sinusoidal excitation are investigated. In the theoretical analysis, van der Pol’s method is applied to determine the expressions for the frequency response curves. In the numerical results, the differences between the responses in single-

Analysis of a Nonlinear Dynamic Vibration Absorber

Journal of Applied Mechanics, 1953
Abstract This paper presents a mathematical analysis of the action of a dynamic vibration absorber. The system analyzed consists of a main mass attached to a rigid foundation by a linear spring coupled to the absorber mass by a spring of nonlinear characteristics.
