摘要
对斜槽式纵-扭复合振动模式压电超声换能器进行了理论及实验研究。推出了换能器的机电等效电路，探讨了槽的倾斜程度对复合超声换能器的共振频率的影响。实验表明，理论预测频率与实测频率基本一致。
The longitudinal-torsional composite transducer with slanting slots was studied. The equivalent circuit for the vibrational system was derived. The effect of the slanting angle of the slots on the resonance frequency of the vibrational system was analyzed. It is concluded that when the slanting angle of the slots was increased, the resonance frequency was decreased. Experimental results show that the measured frequencies are in good agreement with the predicted results.
