Paper Title:
The Study on Mechanical Impedance and Piezoelectric Impedance for Cantilever Beam Based on FEA Method
  Abstract

The mechanical impedance and the piezoelectric coupling impedance response spectrum, the resonant vibration mode and he resonance frequency of the cantilever beam was analyzed by means of FEA for getting the relationship between mechanical impedance and piezoelectric impedance. The results showed that: Through the comparison between the two, both resonance frequency and resonance modes are the same basically, which also showed that the change of piezoelectric impedance changes with the mechanical impedance change. Piezoelectric impedance is the electric reflection of mechanical impedance. It provides a sound theoretical basis and research methods for the piezoelectric impedance damage identification and health monitoring technology.
