Active vibration isolation of electronic components by piezocomposite clamped–clamped beam [PDF]

open access: greenMechanical Systems and Signal Processing, 2011
The sensitive electronic components used in military and aerospace applications endure some intense vibrations. These vibrations have some disturbing effects on the stability and on the service life of these devices. So, protecting these elements becomes a major economic and strategic stake. Vibration isolation can be applied to different levels of the
