摘要

针对在小腔体中阻抗分析仪发射连续波无法准确测得换能器阻抗的问题,提出一种在高静水压下使用脉冲正弦信号激励换能器测量阻抗的方法。以采样电阻法为基础,根据腔体尺寸确定发射脉冲个数以及可测频率范围来有效避免腔体边界反射对测量造成的影响。通过设置不同的发射频率,分别采集换能器两端及采样电阻两端的电压波形信号,利用已知频率的三参数正弦曲线拟合法分别得到波形信号的幅值和初始相位角,计算得到换能器的导纳值。改变静水压力,利用脉冲法测得0～10MPa静水压下换能器导纳特性。实验结果表明,采用脉冲正弦信号激励的方法可在有限空间内准确测量换能器的阻抗特性;且随着静水压力的升高换能器的谐振频率发生偏移,导纳圆直径减小。

Abstract

To solve the problem that electrical impedance of the transducer cannot be measured accurately by the impedance analyzer with continuous wave in small size cavity, a transducer impendence measurement method based on pulse sine signal excitation under high hydrostatic pressure is proposed.Based on the sampling resistance method, the number of sinusoidal pulses and measurable frequency range are determined by the cavity size to effectively eliminate the influence of the boundary reflection.Different transmission frequencies are setted and voltage waveform signals upon the transducer and sampling resistor are collected.The admittance is calculated while the phase difference and amplitude are obtained by three-parameter sine wave curve-fit method.Admittance characteristic is measured with pulse sine signal method under the water pressure ranging from 0 to 10MPa.The experimental results show that sinusoidal pulse method is proved to be a better choice to measure the admittance characteristics of transducers in a limited space, and that the resonant frequency of the transducer shifts, and the diameter of the admittance circle decreases as the pressure increases.
