Damage detection in nonlinear structures using discrete-time volterra series
Structural damage identification is basically a nonlinear phenomenon; however, nonlinear procedures are not used currently in practical applications due to the complexity and difficulty for implementation of such techniques. ...
Nonlinear Dynamic Behavior, Deterministic Chaos and Nonlinear Control of a Micro Electro Mechanical Actuator System (MEMS)
(Destech Publications, Inc, 2015-01-01)
Micro Electro Mechanical Systems (MEMS) are systems composite by electrical and mechanical devices that interact by means of transducers elements, thus constituting one single and whole system. On the study of dynamic ...
On an Active Control for a Structurally Nonlinear Mechanical System, Taking Into Account an Energy Pumping
(Asme-amer Soc Mechanical Eng, 2009-07-01)
The purpose of this work is to investigate the control of the oscillations and the suppression of vibrations in damped and coupled oscillators. In this sense, we look into the potential of using a nonlinear energy sink in ...
A nonlinear electromechanical pendulum arm with a Nonlinear Energy Sink control (NES) approach
This paper considers the nonlinear dynamics of an electromechanical device with a pendulum arm and a Nonlinear Energy Sink (NES) put on the point of the pendulum suspension. It is shown that the (NES) is capable of absorbing ...
Some remarks on bifurcation analysis of a nonlinear vibrating system excited by a shape memory alloy material (SMA)
In this paper, the dynamical response of a coupled oscillator is investigated, taking in consideration the nonlinear behavior of a SMA spring coupling the two oscillators. Due to the nonlinear coupling terms, the system ...
On resonant elliptic systems with rapidly rotating nonlinearities
(Khayyam Publishing, 2012)
We study a Neumann problem for a nonlinear elliptic system. Unlike previous results in the literature of Landesman–Lazer type, our existence theorem allows rapid rotations on the nonlinear term.
SYNCHRONIZATION OF A CLASS OF SECOND-ORDER NONLINEAR SYSTEMS
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2008)
The asymptotic behavior of a class of coupled second-order nonlinear dynamical systems is studied in this paper. Using very mild assumptions on the vector-field, conditions on the coupling parameters that guarantee ...
EXPERIMENTAL OBSERVATION OF NONLINEAR VIBRATIONS USING A CLOSED-LOOP VIBRATION SYSTEM
(Polish Acad Sciences, 2015-12-01)
This paper presents experimental observation of nonlinear vibrations in the response of a flexible cantilever beam to transverse harmonic base excitations around its flexural mode frequencies. In the experimental setup, ...
On the dynamic behaviour of a nonlinear system weakly connected to a linear single degree-of-freedom system
This paper discusses the dynamic behaviour of a nonlinear two degree-of-freedom system consisting of a harmonically excited linear oscillator weakly connected to a nonlinear attachment that behaves as a hardening Duffing ...
