Effects of different driving frequency of longitudinal transducer on flexural vibration characteristics of a circular plate

Using the finite element method(FEM),the first order flexural vibration of a thin circular plate was studied under the excitation of piezoelectric ceramic sandwhiched transducers with unchanged excitation area and different excitation frequencies.The results showed that as the excitation frequency increases,the fundamental frequency of the circular plate flexural vibration increases,while increasing the radius of the circle plate,the amplitude of the lateral displacement increases firstly and then decreases.It was clarified experimentally that the results are consistent with those with FEM basically,they are significant for designers and applications.
