英文摘要：

The lens style shock wave generator is adopted. The mathematics model was established on the basis of the piezoelectric analysis. The resonance frequency of shock ware generator at thickness mode was computed by the finite element software. The calculated results are good agreements with the experimental results of the impedance analyzer,which can supply an effective analyzing tool for the shock wave generator. The effect of the thickness on the resonance frequency is analyzed further,which has guidance to the design and manufacturing of shock wave generator.
