摘要

摘要: 针对目前舰艇声呐维修检测中无法进行换能器动态参数测量的问题, 设计了一种声呐换能器动态参数检测设备。设备以STM32F103作为主控, 通过测试换能器不同小信号频率点上的频率响应, 利用AD5933阻抗分析芯片解算换能器的电导、电纳特性曲线。根据得到的导纳特性曲线, 设计了动态参数解算算法程序, 实现了在不拟合导纳圆的情况下解算动态参数。实际使用结果表明, 该设备携带方便、测试简单, 能够自动完成换能器动态参数的测量, 测量精度可以满足随舰测量指标要求。

Abstract: To conduct measurement of dynamic parameters of a shipboard sonar transducer in maintenance, a device for measuring dynamic parameters of the sonar transducer was developed. STM32F103 was taken as the master control module, and AD5933 impedance analysis chip was adopted to calculate the conductance and admittance of the transducer on the basis of the measured frequency responses of small signals with different frequencies. According to the admittance characteristic curve, an algorithm for calculating the dynamic parameters was proposed and programmed, thus the parameters could be calculated rapidly and accurately without admittance circle fitting. Practical application has shown that this device is portable and is easy in application, and it measures dynamic parameters of sonar transducer automatically with satisfactory accuracy.
