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 ...

Tuned dynamic vibration absorber

The Journal of the Acoustical Society of America, 1997
A vibration absorber is provided for reducing noise and vibration emanating from an electric motor, or another vibrating object, and the surrounding structure to which it is mounted. The vibration absorber has a beam with a mass secured thereto. The vibration absorber is mounted externally to the motor, in a direction perpendicular to an axis of ...

Design of a non-traditional dynamic vibration absorber

The Journal of the Acoustical Society of America, 2009
A non-traditional dynamic vibration absorber is proposed for the minimization of maximum vibration velocity response of a vibrating structure. Unlike the traditional damped absorber configuration, the proposed absorber has a linear viscous damper connecting the absorber mass directly to the ground instead of the main mass.

Platelike Dynamic Vibration Absorbers

Journal of Engineering for Industry, 1975
Platelike dynamic vibration absorbers of novel design are described, and optimum values of their tuning and damping parameters are specified in graphical form. The dynamic absorbers are assumed to comprise either a circular or an annular damped plate that is loaded at its outer perimeter by a rigid annular mass.

Energy harvesting dynamic vibration absorber under random vibration

2013 IEEE International Conference on Control Applications (CCA), 2013
Energy harvesting from structural vibration using piezoelectric material has received much attention in the past few years. The idea is to scavenge energy out of a vibrating host. Coupling energy harvesting with structural vibration control is a challenging task due to conflicting goals.

Improvements in the Optimization of Dynamic Vibration Absorbers

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">Improved formulas are developed for the optimum tuning of damped vibration absorbers whose motion may or may not be in-line with the motion axis of the main mass. J. Ormondroyd and J. P. Den Hartog (1928), studied a class of dynamic vibration absorbers whose motion is in-line with that of the main mass and reported

Dynamics of Vibration Isolation System with a Ball Vibration Absorber

International Applied Mechanics, 2018
The forced vibrations of a mechanical vibration isolation system consisting of a ball vibration absorber (BVA) with linear viscous resistance and a movable carrier body under an external harmonic load are considered. Appell’s formalism is used to formulate and numerically solve the equations of combined motion of the heavy ball without sliding in the ...

Vibration Reduction of a Floating Roof by Dynamic Vibration Absorbers

Journal of Pressure Vessel Technology, 2011
This paper investigates the use of dynamic vibration absorbers as a means to reduce the vibration of a floating roof due to sloshing caused by long-period earthquakes. It is shown that the damping ratio of the primary system caused by the dynamic vibration absorbers increases with rising filling level, hence increasing the probability of liquid ...

Reduction of Ship Vibration by the Dynamic Absorber

Volume 1C: 16th Biennial Conference on Mechanical Vibration and Noise, 1997
Abstract The reduction of main hull vibration of ships by a semiactive dynamic absorber is investigated. The dynamic absorber system includes a moving mass, support springs, dynamic dampers and a control system. Only small electrical power supply is needed for the valve control of the damper and the operation of the control system.
