Figure 10 shows a schematic view of the active tuned vibration absorbers mounted beneath the compressor. The vibration absorbers consist of two discrete masses attached to the ends of two cantilevered beams and are tuned to 50 Hz, which is very close to the frequency of the highest vibration level of the compressor.
Optimum Design of Vibration Absorbers for Structurally
A procedure in designing optimal Dynamic Vibration Absorbers (DVA) for a structurally damped beam system subjected to an arbitrary distributed harmonic force excitation, is presented. The Timoshenko beam theory is used to assess the effects of rotatory inertia and shear deformation.[PDF]

variable stiffness mechanism this research work variable stiffness tuned vibration absorber will be designed to control the vibrations of cantilever beam. As linear theory fails to evaluate the real life results various nonlinear parameters are considered for vibration analysis of cantilever beam with dynamic vibration absorber.
Optimization of an acoustic black hole vibration absorber
Both axes are plotted on a logarithmic scale. Although the beam with an ABH vibration absorber shows an increased number of resonances compared to an unmodified beam, the average value of W ̇ 2 is more than three times lower for the optimal design.Author: Cameron A.

Metamaterial beam with embedded - ScienceDirect
The distribution of vibration absorbers allows the metamaterial beam to be considered as a periodic structure, and due to this property it is possible to study the so-called cell here represented in Fig. 3. This reduces the problem to the segment of the beam comprising a single absorber, whose length a represents the tributary area of theCited by: 8Publish Year: 2018Author: Arnaldo Casalotti, Arnaldo Casalotti, Sami El-Borgi, Sami El-Borgi, Walter Lacarbonara

A new dynamic vibration absorber combining a translational-type absorber and a rotational-type absorber is proposed for isolation of beam vibration under point or distributed harmonic excitation.Author: Muhd. Hafeez Zainulabidin, N. Jaini
Vibration Analysis of a Beam Structure Attached with a
In this paper the transverse vibration of a fixed-fixed end beam will be investigated by experimental measurement. This paper is concerned with the classical theory formula as well as the analysis and design of the dynamic vibration absorber (DVA) which is composed by a flexible beam with two masses symmetrically mounted at its both sides. The fixed end beam clamped to a static structure whereCited by: 3Publish Year: 2013Author: Muhd Hafeez Bin Zainulabidin, N. Jaini

The nonlinear effect incurred by time delay in vibration control is investigated in this study via a vibration absorber coupled with a continuous beam structure. The stability of the vibration absorber coupled structure system with time-delay coupling is firstly studied, which provides a general guideline for the potential time delay to be introduced to the system.Cited by: 1Publish Year: 2016Author: Xiuting Sun, Youshuo Song[PDF]
