摘要：
In this paper, the investigation of piezoelectric unimorph laser shutting system transient vibrations damping is presented. A magnetic force technique and magneto-rheological fluid (MRF) is used for the damping of transient vibrations of the piezoelectric unimorph shutter. A methodology is presented for the analysis and design optimization of piezoelectric unimorph actuator used for laser beam shutting systems. The magnetically coupled piezoelectric unimorph cantilever and disc type piezoelectric unimorph motions are analyzed using a one-dimensional forced harmonic oscillator with a non-linear magnetic spring and MRF damper setting. Using a magneto-rheological effect for damping of transient vibrations the piezoelectric unimorph shutter has been experimentally determined.
