Název v původním jazyce

Modeling and Experimental Test Study of a Multilayer Piezoelectric Actuator

Popis výsledku v původním jazyce

In order to increase the performance of piezoelectric actuators/sensors, a common practice is to stack thin layers of active materials with electrodes in between such that higher electric fields are achieved inside the piezoelectric elements. Modeling this composite material requires either a detailed description of the layers components or the use of equivalent properties. The work presented in this paper achieved a comparative study between these two modeling approaches. The predictions are verified against experimental result. It shows that the both modeling approaches obtain similar results in modal analysis, and in each numerical model, a consistent natural frequency mismatch was found to compare with the experimental modal analysis. A Frequency Response Function (FRF) comparison between experimental measurement and equivalent properties modeling approach also carried out to check its dynamic prediction capability. A simple model updating has been carried out at the end; the updated numerical models exhibit a good consistency with experimental measurement.
