Analysis of Radial Thickness Vibration Modes of Piezoelectric Ceramic Ring Based on ANSYS

Abstract

According to the simulation by Finite Element Analysis (FEA) for rings with different sizes, how thickness vibration resonance frequency varying as piezoelectric ring structure changing is studied. The relation between thickness vibration mode and height, thickness and radius is obtained. The bandwidth of single circle being narrow has been obtained at the same time, so the method that two high frequency piezoelectric ring oscillators are stacked in axis direction and their structure are optimized to get two times as much as the monocyclic bandwidth is researched, according to the trend of single ring.

Research on Vibration Characteristics of Piezoelectric Ceramic Atomizer Based on ANSYS

“…With the inverse piezoelectric effect, the piezoelectric transducer generates highfrequency oscillation deformation when a high-frequency electric field is applied. When the resonant frequency of the piezoelectric crystal is equal to the frequency of the applied electric field, the resonance reaches a mechanical resonance state, which in turn produces high frequency vibration [3]. At this time, the electromechanical energy conversion efficiency is the highest, and the atomizer has the highest working efficiency.…”

Application of ANSYS APDL in the Design of Piezoelectric Transducer

“…The traditional method is to set up the free vibration equation of the piezoelectric plate, and use the analytic method to solve it. However, this method is too complicated, and the results are not intuitive [3].Due to the piezoelectric coupling effect, it is very difficult to carry on the theoretical analysis of the piezoelectric energy transfer film from the perspective of the mechanical and electrical coupling, and most of the work is carried out in special circumstances, and it is difficult to get the explicit solution for general situation. Because of the complex boundary condition and stress state of the piezoelectric ceramic plate, the research on the traditional method is not only time-consuming, but also has a strong limitation [4].…”
