On Lugre Friction Model to Mitigate Nonideal Vibrations
(Asme-amer Soc Mechanical Eng, 2009-07-01)
In this paper, a nonideal mechanical system with the LuGre friction damping model is considered. The mechanical model of the system is an oscillator not necessarily linear connected with an unbalanced motor of excitation ...

Some practical regards on the application of the harmonic balance method for hysteresis models
(2020-09-01)
Describing hysteretic systems with a closed-form solution is a challenging task due to some pitfalls regarding the non-smooth and memory effect mechanisms that do not permit, for example, to apply conventional frequency ...
Modelos autorregressivos para representação de sistemas com histerese
(Universidade Federal de Minas GeraisUFMG, 2016-03-11)
Hysteresis is a highly nonlinear phenomenon commonly found in electromagnetic and electromechanical devices which involve memory efects among the output and the history of the process variables. In sensors and electromechanical ...

Identificación experimental de la fricción en las transmisiones accionadas por cable
(Universidad Nacional de ColombiaManizales - Ingeniería y Arquitectura - Doctorado en Ingeniería - AutomáticaDepartamento de Ingeniería Eléctrica y ElectrónicaFacultad de Ingeniería y ArquitecturaManizales, ColombiaUniversidad Nacional de Colombia - Sede Manizales, 2022)
En esta tesis se propone un modelo de fricción empírico para transmisiones tipo polea-cable que incluye en su formulación, además de la velocidad, el efecto de la carga externa y la relación de transmisión. Los experimentos ...
Diseño de un controlador de estructura variable para el péndulo invertido
(2009-03-18)
RESUMEN: En la presente tesis se presenta el diseño de un Controlador de Estructura Variable (CEV) para un Péndulo Invertido. Se utiliza el procedimiento de Euler-LaGrange para obtener el modelo no lineal del péndulo. Se ...
Identificação automática de atrito em atuadores pneumáticos utilizando equipamento de baixo custo
(Universidade Estadual Paulista (Unesp), 2018-07-27)
O presente trabalho aborda o estudo experimental das características não lineares de atrito interno em atuadores pneumáticos. Os atuadores pneumáticos contêm uma tecnologia limpa comparados com os atuadores hidráulicos, ...
Influence of smart material on the dynamical response of mechanical oscillator
(2014-01-01)
The dynamical response of systems with shape memory alloy (SMA) or magnetorheological damper (MRD) presents a different behavior due to their nonlinear characteristics. Both systems have a nonlinear behavior due to adaptive ...
