Abstract:

The electrical input impedances and acoustic radiation characteristics of magnetostrictive scroll-wound ring transducers were carefully measured and documented to provide experimental data for comparison with theoretical ring-transducer models. Conventional-nickel and cube-textured-nickel rings with equivalent diameter and thickness but with varying lengths were used in the experiment. The data were compared to the theoretical model, NRL EIGSHIP, a computer program of a mathematical analysis of the electroacoustic performance of a single finite-length magnetostrictive circular cylinder submerged in an unbounded medium and radiating sound. The experiment is described, the data are tabulated and plotted, possible sources of error are suggested, and a comparison is made with theory. Author
