An Analytical Modelling to Describe the Coupling Between a Piezoelectric Actuator and a Loading Medium. Validation of the Method for Engineering Problems

Flexural-mode piezoelectric transducers are extensively used as acoustic actuators. The usefulness of equivalent circuit modelling to characterise this kind of piezoelectric source has been long recognised, even the conventional models are empirical or even they assume drastic approximations. The aim of the study is to improve this kind of equivalent network in such a way that it permits to link together the basic physical parameters, avoiding overly intricate formulation even it does not assume usual approximations. The equivalent network obtained shows a classical structure, the expressions of the parameters of the circuit being however known analytically as simple functions of the parameters of the system. In order to valid the modelling, an application is given when loading the piezoelectric source with a resonator.
