超声减摩用压电换能器阻抗匹配的试验研究

对超声减摩特性已进行了一些研究，实验结果表明，当超声振动的振幅越大超声振动的减摩性越好。因此，要使减摩效果达到最好，应使压电振子在谐振点附近工作，使其振幅达到最大。该文讨论了压电换能器的各种匹配电路及其匹配关系并进行了相关实验；结果表明，选择合适的匹配方法，能有效提高压电换能器的性能．

Experiment Study on Inductance Match of Damping Ultrasonic Transducer

we have done some research in ultrasonic vibration damping. The result of many experiments showed that the greater the amplitude of ultrasonic vibration the better the damping result. Therefore, in order to attain the better damping result, the ultrasonic transducer should worked in its resonance frequency to make the amplitude reached the maximum. This paper discussed the matching circuit of ultrasonic transducer and the matching relationship , and we have done some relevant experiment; the result showed that it can improve the performance of ultrasonic transducer if the proper matching circuit selected.
