Abstract:
This paper describes the development of a free-flooding rare-earth iron hexagonal transducer with an outer size of φ160×160 and a weight of 4.9 kg. The vibrations of the rare-earth iron hexagonal transducer and the free-flooding water cavity in it are theoretically analyzed and discussed. The measurement result shows that the transducer may send out a source level of 185 dB, and the resonance frequency of the transducer drops down from 1.90 kHz in air to 0.85 kHz in water because of the cavity resonance. The free-flooding water cavity can therefore not only withstand the hydropressure, but also make the resonance frequency drop down considerably. The free-flooding rare-earth iron hexagonal transducer shows promise to be a lightweight, high-power sound source for operation at great depths in the ocean. [Work supported by CSSC.]
