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 ...

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.

Forced vibrations of a beam with a non-linear dynamic vibration absorber

Journal of Sound and Vibration, 1983
Abstract Forced vibrations of a simply supported beam having an attached non-linear dynamic vibration absorber and excited by sinusoidal motion of its supporting base are investigated analytically. The absorber produces a hardening spring force in the form of a cubic curve. The governing partial differential equation reduces to the well-known Duffing

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.

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 ...

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

Energy Harvesting Dynamic Vibration Absorbers

Journal of Applied Mechanics, 2013
Energy harvesting is a promise to harvest unwanted vibrations from a host structure. Similarly, a dynamic vibration absorber is proved to be a very simple and effective vibration suppression device, with many practical implementations in civil and mechanical engineering. This paper analyzes the prospect of using a vibration absorber for possible energy
