The paper concerns the introduction of cubic nonlinearity into a vibration absorber to improve its effectiveness. The nonlinear stiffness is offered by a thin clamped circular plate which undergoes large flexural deflection. ...

Knowledge of the nonlinear characteristics of a vibration absorber is important if its performance is to be predicted accurately when connected to a host structure. This can be achieved theoretically, but experimental ...

The behavior of a new type of nonlinear dynamic vibration absorber is studied. A distinctive characteristic of the proposed absorber is the impossibility to extend the system to infinity. The mathematical formulation is ...

The purpose of this study is to develop a dynamic vibration absorber using viscoelastic material with nonlinear essential stiffness and time-dependent damping properties for a non-ideal vibrating system with Sommerfeld ...

Delayed feedback (DF) control is a well-established technique to suppress single frequency vibration of a non-minimum phase system. Modal control is also a well-established technique to control multiple vibration modes of ...

Recently, viscoelastic materials have been widely used for vibration control due to their efficacy and flexibility in real engineering problems. Their use as constitutive parts of dynamic vibration absorbers requires the ...

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 ...

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 ...

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 ...

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 ...
