Research on Vibration Characteristics of Piezoelectric Ceramic Atomizer Based on ANSYS

Abstract

In the design and application of ultrasonic atomizer, the resonant frequency and vibration mode of piezoelectric transducer have an effect on the working state and atomization effect of the atomizer. In order to deeply study the piezoelectric ceramic ultrasonic atomizer Vibration characteristics, piezoelectric coupling simulation analysis was performed by ANSYS software, multi-order vibration mode of piezoelectric ceramic atomization sheet obtained by modal analysis method, combined with harmonic response analysis to obtain resonant frequency of piezoelectric ceramic ultrasonic atomization sheet, and analysis the influence of the main size of the atomized sheet on the vibration mode. According to theoretical analysis and experimental tests, the effectiveness of the finite element analysis can be verified, and then provide a theoretical basis for the study of ultrasonic atomizers.
