Abstract

This SBIR Phase I Proposal addresses the need for a low-profile, broad-band, high- performance, shear-mode tonpilz transducer that can operate at deep depths. In one approach we add a special suspension system to the Van Tol/Meyer tonpilz that allows operation at submarine depth with only a small impact on the performance. Two other less conventional approaches which would allow operation at even greater depths are also presented. All three designs are discussed with emphasis placed on the first design using finite element modeling and analysis, including a comparison with the original tonpliz design in addition to a hydrostatic stress analysis. All three designs would be investigated during the Phase I Basic program and the best candidate for the goals of this program would be selected going forward. The finite element analysis program ANSYS will be our main tool allowing us to accurately model, evaluate and compare the various designs with each other.
