Separation of Frequency Coexisting Vibration Signals in Wind Turbines Gearboxes
(Universidade Federal de Santa Maria. Programa de Pós-Graduação em Engenharia Elétrica, 2018-10-21)
In this paper, a method for separation of vibration signals coexisting in the same frequency bin and coming from different mechanicals pieces is presented. A blind source separation method for vibration signals in gearboxes ...
Análise da resposta dinâmica de um sistema mecânico com amortecedor de massa passivo: um estudo experimental e numérico
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em Engenharia CivilUTFPR, 2018-05-30)
Dynamic vibration control is fundamental in noise reduction and structural vibration caused by external loads. If the vibration is excessive it can compromise the physical integrity of the structure, through a fatigue ...
Semi-active friction tendons for vibration control of space structures
(Elsevier, 2014-07)
Semi-active vibration control systems are becoming popular because they offer both the reliability of passive systems and the versatility of active control without high power demands. In this work, a new semi-active control ...

Mechanical vibration preserves bone structure in rats treated with glucocorticoids
(ELSEVIER SCIENCE INC, 2010)
Glucocorticoids are an important cause of secondary osteoporosis in humans, which decreases bone quality and leads to fractures. Mechanical stimulation in the form of low-intensity and high-frequency vibration seems to be ...
An approach to reduce vibration and avoid shimmy on landing gears based on an adapted eigenstructure assignment theory
(2020-01-01)
Landing gear shimmy is a self excited vibration phenomenon which must be avoided during aircraft design due to its potentially catastrophic behaviour. In a preliminary specification of structural properties of a landing ...
