Comparação entre dois tipos de suspensão passiva de barra em condições simuladas de pista de prova normalizada
(Engenharia Agrícola, 2010-07-01) [Artigo]
In this paper we conducted several analysis of the simulated dynamic behavior of two passive suspension types of the trailed sprayer booms. The suspension analysis was conducted under conditions of a bump track test ISO ...
On a control design to an AFM microcantilever beam, operating in a tapping-mode, with irregular behavior
(Proceedings of the ASME Design Engineering Technical Conference, 2011-12-01) [Trabalho apresentado em evento]
In last decades, control of nonlinear dynamic systems became an important and interesting problem studied by many authors, what results the appearance of lots of works about this subject in the scientific literature. In ...
Application of passive control to energy harvester efficiency using a nonideal portal frame structural support system
(Journal of Intelligent Material Systems and Structures, 2014-03-01) [Artigo]
An analysis of a new energy harvester model is presented, based on a simple portal frame structure, considered a nonideal system due to the kind of excitation influenced by the response of the system, such as a direct ...
A note on the use of Melnikov's chaos prediction criterion: results of a friction-driven self-excited vibrating system
(Control of Oscillations and Chaos, Vols 1-3, Proceedings, 2000-01-01) [Artigo]
Use of nonlinear asymmetrical shock absorber to improve comfort on passenger vehicles
(Journal of Sound and Vibration, 2014-03-31) [Artigo]
In this study the behaviour of two different types of shock absorbers, symmetrical (linear) and asymmetrical (nonlinear) is compared for use on passenger vehicles. The analyses use different standard road inputs and include ...
Stick-slip chaos in a non-ideal self-excited system
(Proceedings of the ASME Design Engineering Technical Conference, 2003-12-01) [Trabalho apresentado em evento]
In engineering practical systems the excitation source is generally dependent on the system dynamic structure. In this paper we analyze a self-excited oscillating system due to dry friction which interacts with an energy ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part I-primary resonance and free response at low temperatures
(Nonlinear Dynamics, 2010-03-01) [Artigo]
In this work, the response of a single-degree-of-freedom shape memory oscillator subjected to the excitation harmonic has been investigated. Equation of motion is formulated assuming a polynomial constitutive model to ...
On friction-driven vibrations in a mass block-belt-motor system with a limited power supply
(Journal of Sound and Vibration, 2000-07-20) [Artigo]
Analytical study of the nonlinear behavior of a shape memory oscillator: Part II-resonance secondary
(Nonlinear Dynamics, 2010-06-01) [Artigo]
In Part II of this work, we investigated the dynamics of the shape memory oscillator, in the particular case of the secondary resonances. We used the equation of motion developed in Part I (Piccirillo et al., Nonlinear ...
Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part II: Nonideal energy source
(Nonlinear Dynamics, 2009-05-01) [Artigo]
In Part II of this two-part work, we apply an optimal linear control technique to suppress chaotic behavior in a SMA oscillator, driven by a DC motor with limited power supply (Nonideal sources). Nonideal sources of ...
