摘要
This paper presents the shape deformation of a thin plate coupled to piezoelectric actuators and sensors analyzed using the finite element method (FEM). The coupling effects between electric and mechanical properties of the piezoelectric material draw attention to potential applications, such as actuators, sensors, etc. The proposed method is analyzed and evaluated, and its effectiveness is proven. Firstly, a rectangular piezoelectric actuator with three symmetrically bonded sensors is used. Secondly, it is applied to control the swimming pool diving board. Combination of FEM and LQR active control algorithms through numerical simulation results shows changing shape and position of the piezoelectric patch which makes premises for an experiment and production.
