钹式压电复合换能器的有限元分析(英文)
Finite element analysis on cymbal pi ezocomposite transducer
【摘要】 主要运用轴对称薄壳截锥单元的有限元分析方法,对钹式压电复合换能器的工作模式进行分析,并计算出在电场的作用下,钹式压电复合换能器的纵向位移,以及纵向位移与端帽及压电陶瓷形状参数的关系,并与试验结果进行对比。
【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.
