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 ...
POSITION CONTROL OF A MANIPULATOR ROBOTIC ARM CONSIDERING FLEXIBLE JOINTS DRIVEN BY A DC MOTOR AND A CONTROLLED TORQUE BY A MR-BRAKE
(Proceedings Of The Asme International Mechanical Engineering Congress And Exposition, 2016, Vol. 4b, 2017-01-01) [Trabalho apresentado em evento]
This paper presents a two-degree-of-freedom robotic arm design with flexible joints driven by a DC Motor and controlled by a Magnetorheological (MR) Brake, considering a feedback control. The MR Brake is used to provide ...
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 ...
CONTROL OF SLEWING MOTIONS OF FLEXIBLE STRUCTURES USING SHAPE MEMORY ALLOY
(Asme International Mechanical Engineering Congress And Exposition, 2014, Vol 4b, 2015-01-01) [Trabalho apresentado em evento]
This paper presents the position and vibration control of a single flexible slewing structure driven by a DC motor at the slewing axis. The position is controlled over the current applied to the DC motor armature. To control ...
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 ...
GEOMETRIC MODELING AND ROBUST CONTROL OF A GYROSCOPIC SYSTEM
(International Design Engineering Technical Conferences And Computers And Information In Engineering Conference, 2015, Vol 8, 2016-01-01) [Trabalho apresentado em evento]
Gyroscopic systems are multi-body systems which present coupled three dimensional motion. The configuration space and the state space are differentiable manifolds, and differential geometric concepts are frequently useful ...
