A velocity based active vibration control of hysteretic systems
(2011-01)
Article
Open AccessHysteresis is a property of systems that do not instantly follow the forces applied to them, but react slowly, or do not return completely to their original state. A velocity based active vibration control, along with a ... -

Bearing fault detection by a novel condition-monitoring scheme based on statistical-time features and neural networks
(Institute of Electrical and Electronics Engineers (IEEE), 2013-08)
Article
Restricted access - publisher's policyBearing degradation is the most common source of faults in electrical machines. In this context, this work presents a novel monitoring scheme applied to diagnose bearing faults. Apart from detecting local defects, i.e., ... -
Catalogue of vibration reduction index formulas for heavy junctions based on numerical simulations
(2017-07)
Article
Open AccessThe vibration reduction index (Kij) is a key parameter in the prediction of flanking transmissions according to the EN-12354 standard. Formulas for the evaluation of Kij in L, T and X junctions that depend on the mass ratio ... -
