Characterization and FEM-based Performance Analysis of a Tonpilz Transducer for Underwater Acoustic Signaling Applications
نویسندگان
چکیده
Underwater acoustic signals need transducers to generate and detect signals with high power, linearity, dynamic-range and beamwidth. Among a variety of transducer designs, a Tonpilz transducer stands out for power and long-range applications. A Tonpilz transducer for underwater acoustic signaling is developed to scale and analyzed using FEM tools with Comsol. The underlying pressure-acoustics and piezoelectric phenomena are examined as a function of sizing, transducer dimensioning, materials, and variability. Using FEM tools, we analyze and evaluate key transducer performance specs such as resonant frequency, tunability, material-choices, beam-pattern and scalability. Using Comsol as a design tool, one can develop low-cost, reliable, miniature transducers for sonar signaling and ultrasonic scanners.

متن کاملPerformance of tonpilz transducers with segmented piezoelectric stacks using materials with high electromechanical coupling coefficient.
Tonpilz acoustic transducers for use underwater often include a stack of piezoelectric material pieces polarized along the length of the stack and having alternating polarity. The pieces are interspersed with electrodes, bonded together, and electrically connected in parallel. The stack is normally much shorter than a quarter wavelength at the fundamental resonance frequency so that the mechani...
