On a Nonideal (MRD) Damper-Electro-mechanical Absorber Dynamics
(World Scientific Publ Co Pte Ltd, 2011-10-01)
In this paper, we have investigated the nonlinear dynamic behavior of an electro-mechanical vibration absorber (NEVA), taking into account a modified (MR) Damper (MRD), in its mathematical model, which was excited by a ...
Use of a dynamic absorber in the case of a vibrating printed circuit board of complicated boundary shape
(Academic Press Ltd-elsevier Science Ltd, 2000-02)
An experimental investigation was carried out to examine the feasibility of using a dynamic absorber when a printed circuit board (PCB) of complicated boundary shape operates under resonance conditions. The dynamic response ...

Demonstration of non-collocated vibration control of a flexible manipulator using electrical dynamic absorbers
(Iop Publishing Ltd, 2013-12-01)
This paper describes an experimental study into the vibration control of a servo system comprising a servo motor and a flexible manipulator. Two modes of the system are controlled by using the servo motor and an accelerometer ...
Optimal and robust modal control of a flexible structure using an active dynamic vibration absorber
(Iop Publishing Ltd, 2011-04-01)
This paper is concerned with feedback vibration control of a lightly damped flexible structure that has a large number of well-separated modes. A single active electrical dynamic absorber is used to reduce a particular ...

Optimal parameters and characteristics of a three degree of freedom dynamic vibration absorber
(American Society of Mechanical Engineers, 2012-04)
The present study is devoted to the determination of the optimal parameters and characteristics of a three degree of freedom dynamic vibration absorber (3 DOF DVA) for the vibration reduction of a plate at a given point. ...
Controle de vibrações livres utilizando absorvedores de líquido sintonizado
(Universidade Federal de Santa MariaBrasilUFSMUFSM Cachoeira do Sul, 2021-11-24)
Vibration mitigation can be achieved by using various damping systems, they can be active
hybrid or passive. Dynamic vibration absorbers are tuned to the structure and they are
responsable of energy dissipation. With new ...
Robust broadband vibration control of a flexible structure using an electrical dynamic absorber
(Iop Publishing Ltd, 2011-07-01)
This paper presents a simple but practical feedback control method to suppress the vibration of a flexible structure in the frequency range between 10 Hz and 1 kHz. A dynamic vibration absorber is designed for this, which ...
Stiffness nonlinearity in structural dynamics: Our friend or enemy?
(2017-04-25)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. Primarily this has been because this type of nonlinearity can cause unpredictable dynamics, and ...
