Abstract:

The Phase I effort successfully developed an integrated magnetostrictive transducer/amplifier module concept to meet these performance goals: broad bandwidth (7-30 kHz), compact size (approximately 1/2 wavelength at the center frequency), at least 30 Watts output power, and high efficiency. Conceptual designs of the transducer, amplifier, and the integrated transducer module developed during Phase I will be proven with hardware demonstrations during Phase II. The transducer is a hybrid Terfenol-D/Galfenol multiresonant tonpilz. The amplifier is a compact version of QorTek's proprietary amplifier technology. Broadband performance was achieved by switching phase of the mechanical response between the Terfenol-D and Galfenol at a specified frequency which can be implemented in the amplifier and control electronics. In order to demonstrate the integrated transducer technology, the following objectives must be achieved in the proposed work: Objective 1. Validate transducer and amplifier behavior using modeling and limited hardware demonstrations. Objective 2. Demonstrate the integrated transducer/amplifier by building and testing integrated transducer modules. (Option 1) Objective 3. Design an array of integrated modules to demonstrate capabilities of the module. (Option 2) Objective 4. Demonstrate the technology to enable review and adoption by Navy transition program offices.
