Influence of ideal and non-ideal excitation sources on the dynamics of a nonlinear vibro-impact system
(Journal of Theoretical and Applied Mechanics, 2013-01-01) [Artigo]
The objective of the present work is to analyze the dynamics of a vibro-impact system consisting of two blocks of different mass coupled by a spring with two stages. Two different types of excitation sources for the system ...
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 ...
Contribution of electrical parameters on the dynamical behaviour of a nonlinear electromagnetic damper
(Nonlinear Dynamics, 2015-02-01) [Artigo]
This study explores the dynamical behaviour of electromechanical systems used as vibration absorber. A nonlinear system is considered, with the nonlinearity coming from Duffing-type stiffness. The mathematical modelling ...
ON DYNAMIC MODELLING OF COMPRESSED AIR ENGINE WITH CONNECTING- ROD-CRANK TO CONTROL ANGULAR POSITION OF OSCILLATING ROTATION
(Proceedings Of The Asme International Mechanical Engineering Congress And Exposition, 2016, Vol. 4b, 2017-01-01) [Trabalho apresentado em evento]
In this work is examined the dynamic behavior and the controllability of a compressed air engine with a connecting rod-crank. The pneumatic motor is composed by a mono cylinder, a connecting-rod and a control crank to the ...
Non-ideal system with quadratic nonlinearities containing a two-to-one internal resonance
(Proceedings of the ASME Design Engineering Technical Conference, 2016-01-01) [Trabalho apresentado em evento]
The dynamical behaviour of a non-ideal three-degrees-offreedom weakly coupled system associated with the quadratic nonlinearities in the equations of motion is investigated. The main system consists of two nonlinear ...
NON-IDEAL SYSTEM WITH QUADRATIC NONLINEARITIES CONTAINING A TWO TO-ONE INTERNAL RESONANCE
(Proceedings Of The Asme International Design Engineering Technical Conferences And Computers And Information In Engineering Conference, 2016, Vol 8, 2016-01-01) [Trabalho apresentado em evento]
The dynamical behaviour of a non-ideal three-degrees-of freedom weakly coupled system associated with the quadratic nonlinearities in the equations of motion is investigated. The main system consists of two nonlinear ...
