The Theoretical Study of a Mechanical Model for Bonded PZT Actuator

In this paper, a mechanical model for bonded PZT actuator is presented. By analysis (analyzing) and researching principles of the bonded PZT drive combined with the second class of piezoelectric force - electric coupled constitutive equations based on continuum dynamics established along the length of PZT-driven model to the mechanical vibration. In (during) the modeling process, the impact of the bonding layer was mainly considered between the PZT and the structure.
