| Abstract: | The radial thickness vibration of piezoelectric ceramic ring has been analyzed in this paper,and the resonance and anti-resonance frequency equations have been derived using the piezoelectric theory and mechanical vibration theory.The resonant frequencies are obtained by using the image method,and the error between the actual measurement result and the theoretical result is less than 1%.The piezoelectric ceramic ring vibration modes have also been analyzed by the finite element analysis(FEA) software.A comparison of results obtained from the theory and FEA shows that theory and experiment has good agreement. |
