Summary

Abstract.

The reliability of thick 1-3 piezoelectric composite substrates under high drive conditions was experimentally investigated. Three prototype transducer aperture dimensions commensurate with typical tonpilz designs were studied. However, unlike a typical tonpilz configuration, all three designs were backed with an absorptive material, and relied on bond joint integrity rather than a tie rod. Low level measurements taken on the multi-layered designs indicate these simple designs afford a large operational bandwidth. In one set of measurements the various transducer elements were driven using a 20 kW power amplifier (3000Vrms at 1.5% duty cycle) with peak transducer input powers ranging from 4.0 to 7.4 kW. Another set of endurance measurements investigated higher duty cycles (up to 10%) at a lower drive level (1 000Vrms). The results suggest that the use of Navy type IV (PZT-5H) piezoceramic in a thick (25 mm) 1-3 piezoelectric composite is suitable for low to moderate duty cycle, pulsed, high drive transmit signals.
