Acoustic Transducer

A wide-band cylindrical transducer was developed by using the wide band of the composite material and the matched matching layer for multimode coupling. Firstly, the structure size of the transducer’s sensitive component was designed by using ANSYS simulation software. Secondly, the piezoelectric composite ring-shaped sensitive component was fabricated by the piezoelectric composite curved-surface forming process, and the matching layer was coated on the periphery of the ring-shaped piezoelectric composite material. Finally, it was encapsulated and the electrodes were drawn out to make a high-frequency broadband horizontal omnidirectional water acoustic transducer prototype. After testing, the working frequency range of the transducer was 230–380 kHz, and the maximum transmission voltage response was 168 dB in the water.

Ceramic Cylinder

A new type of piezoelectric composite ultrasonic transducer with high frequency in radial vibration is studied. A high-frequency acoustic transducer has been designed and prepared with pzt-5-type piezoelectric ceramic cylinder. When the piezoelectric ceramic cylinder vibrates along the direction of its radial direction, the working frequency is high. It is composed of a piezoelectric ceramic tube and a steel bracket which is inserted in the inner of the ceramic tube. Use the finite element method by ANSYS for analyzing the radial vibration of a piezoelectric tube. On that basis, through managing ANSYS simulation the vibration mode of transducer system is obtained, and analyzed the working frequency of transducer. According to the simulation, the high-frequency cylindrical acoustic transducer has been produced. Comparing the products and the traditional cylindrical transducers, the products haven’t only a good all-round circle directional, but it also has a high working frequency (300 kHz).

1-3-2 piezoelectric composite has been widely used in the field of underwater acoustic transducer. In this paper, Series-parallel model is used to make the theoretical derivation of the resonant frequency of 1-3-2 piezoelectric composite. By using numerical calculation the law of the frequency varying with the cutting depth is gained. It provides theoretical basis for the design of the 1-3-2 piezoelectric composite with multi-mode.

AbstractAccurate determination of sensitivity and directivity is important for any underwater acoustic transducer. In this work, an automatic measuring platform was designed and implemented for characterizing underwater acoustic transducers. The overall hardware setup includes a PXI (PCI Extensions for Instrumentation)-based data acquisition system, computer-based controller module, motion controller module, and LabVIEW-based automatic calibration program. The system performs a sequence of operations automatically and achieves synchronous control of transmission and acquisition of real-time acoustic signals as well as processing, recording, and report generation. This measurement platform can be utilized for characterizing any type of acoustic transducer for its receiving sensitivity, transmitting response, and directivity measurement as per IEC60565 standard. The measurement results for RESON TC4034 and RESON TC 2080 transducers are presented and the results show that the system is able to carry out accurate calibration and characterization of any underwater acoustic transducer. Sources of uncertainty for calibration are also presented with the confidence level of approximately 95%.
