ملخص

Terfenol-D resonant transducers have some advantages, such as high energy density and high vibrational amplitude, that make them suitable for working in a wide range of application. On the contrary, the main drawback is that operating frequency is fixed and correspond to the resonance frequency of the device itself. If working frequency is far away from the resonance, efficiency of the transducer decreases suddenly. In this paper, an attempt to design and simulation of a multi-resonance sonic transducer is presented. The idea is to increase the range of operating frequencies of about 1.5 kHz. This can be obtained by exploiting ΔE effect in Terfenol-D in response to changes in mechanical preload and magnetic bias. Design procedure is validated by a finite element commercial software and effects of changing resonance frequency in vibrational mode shape of the transducer are presented. The magnetic circuit of the transducer is designed to minimize flux leakage and it is simulated with ANSYS12. Results of this paper can help to design the more flexible transducer in operating frequency and modal shape.
