Exploiting nonlinearity to improve the effectiveness of a vibration neutralizer
(2012-01-01)
This paper present a study on the use of geometric stiffness nonlinearity to improve the effectiveness of a vibration neutralizer attached to a machine subject to harmonic excitation. It is assumed that the machine acts ...
Nonlinear dynamics and control strategies: On a energy harvester vibrating system with a linear form to non-ideal motor torque
(E D P Sciences, 2012-01-01)
In this paper, we deal with the research of a vibrating model of an energy harvester device, including the nonlinearities in the model of the piezoelectric coupling and the non-ideal excitation. We show, using numerical ...
Suppression of chaotic vibrations in a nonlinear half-car model
(2014-12-10)
The present work investigates the nonlinear response of a half-car model. The disturbances of the road are assumed to be sinusoidal. After constructing the bifurcation diagram, we using the 0-1 test for identify the chaotic ...

EXPLOITING THE TRANSIENT RESPONSE OF A SINGLE DEGREE-OF-FREEDOM OSCILLATOR FOR THE PURPOSE OF ENERGY HARVESTING
(Int Inst Acoustics & Vibration, 2015-01-01)
Vibration-based energy harvesters have been intensively studied recently because of the need to power wireless devices or to augment the use of batteries. When time-unlimited harmonic excitation is provided to a single ...
On the dynamics behavior and a control design to a nonlinear 2-DOF vibrating gyroscopic-MEMS model
(2011-12-01)
In this paper, we deal with the nonlinear dynamics, the transfer of energy and control of the vibrations of a Micro Electro-mechanical System (MEMS) gyroscope. The MEMS are micro-transducers whose operation is based on ...
A non-linear stiffness experimental device for shock isolation
(2013-01-01)
Shock vibration is a common problem involving large forces and accelerations, usually resulting in non linear behavior. Normally shock isolation systems are modeled eith linear passive stiffness elements intended to absorb ...
