PHENOMENA AND BIFURCATION ANALYSIS OF AN AEROELASTIC SYSTEM WITH IMPACT EFFECTS
(Amer Soc Mechanical Engineers, 2014-01-01)
Impacts can happen in real aircraft movable surfaces, such as ailerons, flaps, rudder, elevators, trim tabs among others secondary control surfaces leading to complex, dangerous and unpredictable transitions. In a real ...
VIBRATION TRANSMISSIBILITY IN SYSTEMS WITH NONLINEAR DAMPERS
(Int Inst Acoustics & Vibration, 2015-01-01)
Dampers are used in mechanical systems to isolate them from vibration, mainly to dissipate energy and to lower the amplitude of the system behavior near the resonance frequency. However, the use of linear dampers with ...
NON-IDEAL SYSTEM WITH QUADRATIC NONLINEARITIES CONTAINING A TWO TO-ONE INTERNAL RESONANCE
(Amer Soc Mechanical Engineers, 2016-01-01)
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 ...
Phenomena and bifurcation analysis of an aeroelastic system with impact effects
(2014-01-01)
Impacts can happen in real aircraft movable surfaces, such as ailerons, flaps, rudder, elevators, trim tabs among others secondary control surfaces leading to complex, dangerous and unpredictable transitions. In a real ...
Thermographic inspection using a microcontroller-based camera positioning system
(2015-01-01)
Infrared thermal cameras can be used to detect early-stage thermal anomalies in electrical or mechanical equipment and structures, before they lead to the interruption of their operation. In this work, we present a system ...
POSITION CONTROL OF A MANIPULATOR ROBOTIC ARM CONSIDERING FLEXIBLE JOINTS DRIVEN BY A DC MOTOR AND A CONTROLLED TORQUE BY A MR-BRAKE
(Amer Soc Mechanical Engineers, 2017-01-01)
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 ...
A nonlinear and non-ideal wind generator supporting structure
(2006-10-09)
We present a simple mathematical model of a wind turbine supporting tower. Here, the wind excitation is considered to be a non-ideal power source. In such a consideration, there is interaction between the energy supply and ...
Study of the (D)over-barN Interaction in a QCD Coulomb Gauge Quark Model
(E D P Sciences, 2009-01-01)
We study the (D) over barN interaction at low energies with a quark model inspired in the QCD Hamiltonian in Coulomb gauge. The model Hamiltonian incorporates a confining Coulomb potential extracted from a self-consistent ...
Position control of a manipulator robotic arm considering flexible joints driven by a dc motor and a controlled torque by a mr-brake
(2016-01-01)
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 ...
