“…In the open-circuit and short-circuit states, the second natural frequencies of the actuator system are defined as f open and f short and measured respectively to calculate the generalized electromechanical coupling coefficient K 31 , that are then obtained as f open = 2390.96 Hz and f short = 2360.27 Hz. Then K 31 = 0.161 78 is achieved according to equation (7). The inherent capacitor C p of the shunting PZT is 2.925 nF.…”

“…Abdullah [6] indicated that, although a secondary stage actuator placed near the headslider can solve some vibration problems of HDDs, its cost and fragility are critical factors delaying the commercial production of such drives. In the study of passive vibration control approaches, Liu [7] developed a finite element model to obtain the dynamic properties of HDD covers and their antivibration/shock and anti-acoustics performances were studied by a constrained layer damping treatment. The effect of essential design parameters on the dynamics properties of the cover was also investigated.…”
