On an Active Control for a Structurally Nonlinear Mechanical System, Taking Into Account an Energy Pumping
(Asme-amer Soc Mechanical Eng, 2013)
Full modeling of the mooring non-linearity in a two-dimensional floating structure
(Pergamon-Elsevier Science Ltd, 2006-01-05)
The dynamic behavior of a two-dimensional model of a small floating structure anchored by chains is analyzed. The structure is first modeled as a two-degrees-of-freedom oscillator with a strongly non-linear stiffness and ...
Non-parametric identification of a non-linear buckled beam using discrete-time Volterra Series
(European Assoc Structural Dynamics, 2015)
Application of Volterra series in nonlinear mechanical system identification and in structural health monitoring problems
(Universidade Estadual Paulista (UNESP), 2016)
Nonlinear reduced-order modeling and bifurcation analysis of whirl flutter in a rotor-nacelle system
(2020-01-01)
Whirl flutter is an aeroelastic instability that can be affected by structural or/and aerodynamic nonlinearities. This instability may lead to potentially dangerous behaviors. In this study, a nonlinear reduced-order model ...
Updating of a nonlinear finite element model using discrete-time volterra series
(2017-01-01)
In this study, the discrete-time Volterra series are used to update parameters in a nonlinear finite element model. The main idea of the Volterra series is to describe the discrete-time output of a nonlinear system using ...
Nonlinear dynamics of rotating box FGM beams using nonlinear normal modes
(Elsevier, 2013-01)
In this work an analysis is performed on the nonlinear planar vibrations of a functionally graded beam subjected to a combined thermal and harmonic transverse load in the presence of internal resonance. Adopting the direct ...
A brief comment on the dynamical behavior of a forced nonlinear slewing beam: 1. Superharmonic resonance
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2005-06)
This paper describes the dynamical behavior of a nonlinear flexible beam (cubic nonlinearities considered) connected to a dc motor (responsible for the slewing motion) when the angular displacement of the slewing axis and ...
Remarks on an Optimal Linear Control Design Applied to a Nonideal and an Ideal Structure Coupled to an Essentially Nonlinear Oscillator
(Asme-amer Soc Mechanical Eng, 2010-04-01)
This paper considers a nonlinear dynamics of a particular structure coupled (or uncoupled) to an essentially nonlinear oscillator. We used an optimal linear control design to reduce the amplitude of oscillations and to ...
