Abstract :
In this paper, using the finite element software ANSYS, the structural parameters of Janus-Helmholtz transducer were optimized to obtain excellent acoustic radiation properties in range of 2-5kHz. Based on optimization results produced a Janus-Helmholtz transducer test prototype, test results show that the simulation results and experimental results are basically consistent, verified Janus-Helmholtz transducer is an ideal low-frequency, broadband, high power, small size, deep water transducer.
