A Kind of Minitype 2D Vector Hydrophone

Abstract:

A special designed 2D accelerometer was successfully used in the design of the minitype 2D vector hydrophone. The theory, design and experiment test data of both the accelerometer and the vector hydrophone was presented in this paper. The accelerometer based on cantilever beam mode and used PZT tube to substitute the PZT plate which was traditional used, this substitution enhanced the mechanical strength of the accelerometer, which resulted to the high performance of the 2D vector hydrophone in its natural frequency and sensitivity. The outside electrode of the PZT tube was divided into four equivalent parts, and each opposite part was wiring connected into one accelerometer channel, thus the two orthotropic accelerometer channels was integrate into one 2D cantilever beam mode accelerometer. The minitype vector hydrophone was designed based on this compact 2D accelerometer, and it’s high performace makes it possible to be used in under water sonar transducer arrays.
