Regarding to complexity and time-consuming analyses of vibration of smart structures, existing classical models are often insufficient. Nowadays, artificial intelligence tools are used for modeling such complex phenomena. The theoretical model is a three-layer piezoelectric composite beam that behaves as an axial actuating mechanism. This actuator consists of an elastic core sandwiched between two piezoelectric active outer layers. The piezoelectric layers are polarized transversely, i.e., the polarization vector is parallel to the applied electric field intensity vector. For initializing the electromechanical effect, an electric field is applied to the piezoelectric layers. The finite element modeling is constructed using ANSYS. Then, harmonic and dynamic vibration analyses are performed and the responses of smart beam are calculated. The required data used for artificial intelligence were collected from vibration analyses. Obtained results demonstrate that artificial neural network is in good agreement with observed values.}, number={1}, journal={Majlesi Journal of Electrical Engineering}, publisher={OICC Press}, author={Ebrahimi, Sepideh and Shahbazi, Somayyeh and Shahbazi, Yaser and Delavari, Ehsan}, year={2024}, month={Feb.}, keywords={Artificial Neural Networks, Islamic Azad University, Young Researchers Club, Piezoelectric actuators, Harmonic and Dynamic Vibration.
