• Abstract

  Two effective strategies of ensuring the safety, robustness and structural health of mechanical systems are fault detection and vibration attenuation. Dynamic vibration absorbers (ADV's) are widely employed on the vibration attenuation in structures, but they do not show satisfactory results in systems with variation of the excitation frequency, since they are limited in the frequency ban…

• Abstract

  Rotating systems are subject to external and internal excitations that cause undesirable vibrations, taking to degradation of the structural integrity of the system and the users health. In the industrial area, for example, the vibration attenuation can allow rotating systems to operate more efficiently and safely, providing less frequent periodic maintenance and avoiding expensive cost. …

• Abstract

  Structural vibration suppression has been the focus of several researches, mainly for developing high performance mechanical systems. Besides classical techniques, which usually involve passive, semi-active and active approaches, the use of periodicity concept for physical and geometric properties is an interesting alternative to get efficient design of systems for several problems. In ge…
