Robust broadband vibration control of a flexible structure using an electrical dynamic absorber
(Iop Publishing Ltd, 2011-07-01)
This paper presents a simple but practical feedback control method to suppress the vibration of a flexible structure in the frequency range between 10 Hz and 1 kHz. A dynamic vibration absorber is designed for this, which ...
High-Frequency, Low-Intensity Vibrations Increase Bone Mass and Muscle Strength in Upper Limbs, Improving Autonomy in Disabled Children
(WILEY, 2011)
Disuse osteoporosis in children is a progressive disease that can affect quality of life. High-frequency, low-magnitude vibration (HFLMV) acts as an anabolic signal for bone and muscle. We undertook a prospective, randomized, ...
Vibratory noise to the fingertip enhances balance improvement associated with light touch
(SPRINGER, 2011)
Light touch of a fingertip on an external stable surface greatly improves the postural stability of standing subjects. The hypothesis of the present work was that a vibrating surface could increase the effectiveness of ...
The effect of actuator and sensor placement on the active control of rotor unbalance
(2003-07-01)
This paper investigates both theoretically and experimentally the effect of the location and number of sensors and magnetic bearing actuators on both global and local vibration reduction along a rotor using a feedforward ...
Experimental Active Vibration Control in Truss Structures Considering Uncertainties in System Parameters

Controle da vibração de transporte vertical considerando a aplicação de amortecedores magneto-reológicos
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2017-04-24)
This work aims to present a study of a vertical transportation of high performance system, as vibration levels with its displacement at higher speeds are uncomfortable to passengers. To the reduction of these vibrations, ...
Controle de vibrações em rotores flexíveis utilizando fios de liga com memória de forma
(Universidade Estadual Paulista (Unesp), 2018-09-28)
Os sistemas rotativos estão frequentemente sujeitos a excitações externas e internas que provocam vibrações indesejáveis, colocando em risco a própria integridade estrutural do sistema e até mesmo a saúde dos usuários. No ...
