Abstract:Abstract: Using finite element method(FEM), piezoelectric ceramic sandwiched transducers of unchanged excitative area and different frequencies incentives a thin circular plate that produces a first-order flexural vibration, which is studied. The results show that as the excitation frequency increases, fundamental frequency of the circular flexural vibration has also increased, while also increasing the radius of pitch circle, the amplitude of lateral displacement increases firstly and then decreases. It was clarified experimentally that the results are consistent with the FEM basically, which are significant for the designers and applications.
