Paper Abstract

The theory of an electrically tunable Terfenol-D vibration absorber is developed in this paper. An overview of mangetostriction including discussion of the (Delta) E effect is presented. Experimental results showing agreement with prior art are included that demonstrate electrical control of a magnetostrictive actuator resonant frequency by varying the resonance between 1275 Hz and 1725 Hz. The tunability of the transducer resonant frequency is then implemented to achieve high bandwidth tunability in the performance of a Terfenol-D vibration absorber.
