Vibration Reduction of the Optical Disk Drive Using Piezoelectric Shunt
압전 션트회로를 이용한 광 디스크 드라이브의 진동 저감
Abstract
This paper presents a piezoelectric shunt methodology to reduce unwanted vibration of optical disk drive(O.D.D.). After briefly investigating a second-order mechanical vibration absorber model, the O.D.D. structure is incorporated with the piezoelectric shunt circuit. In order to identify modal parameter of the structure, a finite element analysis is undertaken. The parameters are optimally tuned on the basis of the circuit model. The displacement transmissibility is evaluated and compared with various resistance values.
