Passive, Adaptive and Active Tuned Vibration Absorbers—A Survey

Abstract

An overview of the recent development of tuned vibration absorbers (TVAs) for vibration and noise suppression is presented. The paper summarizes some popular theory for analysis and optimal tuning of these devices, discusses various design configurations, and presents some contemporary applications of passive TVAs. Furthermore, the paper also presents a brief discussion on the recent progress of adaptive and semi-active TVAs along with their on-line tuning strategies, and active and hybrid fail-safe TVAs.

Vibration Attenuation of Plate Using Multiple Vibration Absorbers

“…The latter approach using discrete masses or known as passive vibration absorbers, however, are more sound because they do not contribute significant additional vibration energy to the structure, besides demonstrated to yield substantial attenuation in structural vibration [8][9][10]. Nevertheless, it produces drawbacks such as the obvious weight increase, and improperly placement and frequency tuning of vibration absorber may result in large increase of vibration level [9,10]. The idea of passive vibration absorber emerges due to a common vibration issue existed in engineering structural applications.…”

Optimisation of dynamic vibration absorbers to minimise kinetic energy and maximise internal power dissipation

“…The damping of the device should also be as low as possible in this case, so that it presents the greatest impedance to the host structure at the operating frequency. The device is then often known as a "vibration neutraliser", and considerable ingenuity has been put into tuning the natural frequency of the device to track variations in the excitation frequency [4,7,10].…”

“…Such devices were originally patented in 1911 [2]. They are widely used to control the vibration of civil [3][4][5], marine [6] and aerospace [7][8][9] structures and can operate in different ways depending on the application. The first way of operating such a device aims to suppress the vibration only at a particular forcing frequency, in which case the devices natural frequency is tuned to this excitation frequency.…”

Vibration Isolation of Lumped Masses Supported on Beam by Imposing Nodes Using Multiple Vibration Absorbers

“…Their vibration absorber consisted of a tuned spring-mass used to suppress the response of a harmonic oscillator. An excellent survey of passive, semi-active and active dynamic vibration absorbers was prepared by (Sun et al, 1995). Spring-mass systems which are used as vibration absorbers to minimize excesses vibrations in continuous structure have received considerable interest in recent years.…”
