【摘要】：壓電陶瓷在壓電換能器中應(yīng)用廣泛,其振動模式和頻率對壓電換能器的工作狀態(tài)及結(jié)構(gòu)參數(shù)有著巨大影響,在對換能器設(shè)計和改良的過程中,如何得到共振頻率及狀態(tài)是需要解決的問題。借助ANSYS15.0,通過模態(tài)分析得到了軸向極化壓電陶瓷圓片的振動變形云圖,在此基礎(chǔ)上進行諧響應(yīng)分析,得到了壓電陶瓷圓板的徑向共振頻率。通過與解析法得到的理論值及理想圓板共振頻率值對比發(fā)現(xiàn)ANSYS軟件在解決此類問題的有效性及便捷性。
[Abstract]:Piezoelectric ceramics are widely used in piezoelectric transducers. Its vibration mode and frequency have great influence on the working state and structural parameters of piezoelectric transducers. In the process of design and improvement of piezoelectric transducers, It is necessary to solve the problem of how to get resonance frequency and state. By means of ANSYS 15.0, the vibration deformation cloud diagram of axially polarized piezoelectric ceramic wafer is obtained by modal analysis, and the harmonic response analysis is carried out on this basis. The radial resonance frequency of piezoelectric ceramic circular plate is obtained and compared with the theoretical value obtained by analytical method and the resonance frequency value of ideal circular plate, it is found that ANSYS software is effective and convenient in solving this kind of problems.
