| Abstract: | The operation model of cymbal piezo composite transducer was studied by using finite element analysis method on axisymme trical thin shell truncated conical unit.The longitudinal dis -placements of cymbal piezocomposite transducer under applied electric field were calculated,and its dependence on the dimensions of m etal endcap and piezoelectric ceram ic disk was also analyzed.The theoretical results were compared with the experimental results. |
