چکیده مقاله
One of the major limitations of using Terfenol D in magnetostrictive actuators and sensors is its magnetic hysteresis This study presents a new empirical model to predict the magnetic hysteresis of Terfenol D at different frequencies by using Hyperbolic Tangent model Initially, an experimental setup was fabricated and used to obtain different magnetic hysteresis curves of Terfenol D; such as major, minor and reversal loops Then, it was shown that the Hyperbolic Tangent model is precisely capable of modeling the magnetic hysteresis of the Terfenol D for both rateindependent and rate dependent cases Empirical equations were proposed with respect to magnetic field frequency which can calculate the non dimensional coefficients needed by the model These empirical equations were validated at new frequencies of 100 Hz and 300 Hz The model can predict the rate dependent hysteresis as well as rateindependent hysteresis and reduces the required experiments and errors due to numerical differentiations generally needed by traditional models
