摘　　要：根据超声波强化氰化浸金的反应环境和声场要求,选用夹心式径向振动压电换能器理论模型,初步计算换能器的谐振频率,并采用有限元仿真软件分析单个换能器振子的振动模态和谐响应,从而对理论模型的计算结果进行修正和补充.根据超声波强化提金工艺的具体工况要求,充分考虑换能器的密封性能和冷却性能,对换能器的装配结构进行优化和微调.样机实验表明:该夹心式径向振动压电换能器的有效工作频率约为28.075 kHz,满足超声波强化氰化提金要求;压电振子品质因数达511.4,换能器性能良好.Based on the reaction environment and sound field requirements of ultrasonic enhanced cyanide leaching gold, a sandwiched radial vibration piezoelectric transducer is used to preliminarily calculate the resonant frequency of transducer. Finite element simulation is conducted for vibration modal and harmonic response analysis, which provides revise and supplement for the pure theoretical model. Finally, according to the specific working conditions of ultrasonic enhanced cyanide gold extraction process, the study fully considers the sealing and cooling requirements of the transducer and optimizes its assembly structure. Experimental results of the prototype show that the effective working frequency of the sandwiched radial vibration piezoelectric transducer is about 28.075 kHz, which properly meets the requirements of ultrasonic enhanced cyanide gold extraction. And its quality factor can reach 511.4, which means good performance of this transducer.
