中文摘要:
      本文对夹心式纵-扭复合振动模式压电超声换能器进行了研究.从换能器的等效电路出发,在无耦合时,得出了换能器中纵向振动模式及扭转振动模式的各自共振频率方程.实验表明,换能器各自共振频率的测试值与理论计算值基本符合.
英文摘要:
      The resonance frequencies of a sandwiched longitudinal-torsional composite piezoelectric ultrasonic transducer is studied in this paper. The respective frequncy equa tions of the longitudinal and torsional vibrations are dreived based on the one dimensional equaivaluent circuit, without considering the coupling between the two types of vibration. Experiments show that the measured resonance frequencies are in good agreement with the computed results.
