通过对Cymbal换能器压电陶瓷片受力分析,给出了其压电方程的边界受力约束条件,建立了Cymbal型压电换能器电压-位移函数关系模型。模型计算结果与试验结果吻合。并利用该模型,给出了Cymbal换能器几个关键参数对等效压电常数de33的影响规律。这些结论对Cymbal换能器的敏感参数误差控制、大批量生产工艺优化、性能指标一致性控制等方面具有指导意义。
Based on the force analysis of Cymbal transducer piezoelectric ceramics, the boundary force constraints of the piezoelectric equation are given, and the voltage-displacement function relationship model of Cymbal piezoelectric transducer is established. The model calculation results are in good agreement with the experimental results. By using this model, the influences of several key parameters of Cymbal transducer on the equivalent piezoelectric constant de33 are given. These conclusions are instructive for the control of sensitive parameters of Cymbal transducer, the optimization of mass production process and the consistency control of performance index.
