In this research, using the energy approach, a generalized dynamic model is derived for Galfenol (Iron-Gallium Alloy) based on the mechanical strain theory and the Jiles-Atherton model. Experiments have been conducted to measure the relationship between the strain and the magnetic field. Using experimental data, unknown parameters in the model have been identified by a developed optimization algorithm. Results show that the novel dynamic model with identified parameters is capable of describing the performance of the Galfenol rod. Simulation and experiment dynamic responses of Galfenol rods are derived. The simulation and the experiment both agree that the magnitude of the strain output decreases with the increase of the excitation frequency.

“…The Jiles-Atherton model [21] quantifies the total magnetization of a ferromagnetic material as the sum of an irreversible component due to domain wall motion and a reversible component due to domain wall bowing. Due to its ease of implementation it has been commonly used to model actuators based on Terfenol-D loaded unidirectionally [22,23]. Another approach to modeling Terfenol-D was formulated by Armstrong et al [24] where bulk magnetization and magnetostriction are derived from an expected value of a large number of moments.…”

“…Evans and Dapino (2011) studied the dynamic model for three-dimensional (3D) magnetostrictive transducers. Huang et al (2007) incorporated the frequency-dependent hysteresis and the magnetomechanical behaviors of magnetostrictive transducer into magnetoelastic dynamic strain model. It was demonstrated that this model can describe the strain for the transducer over a broad range of operation conditions.…”

For the purposes of estimation and control of the vibration amplitude in rotary ultrasonic machining, the relation between vibration amplitude and excitation signal was examined. The mechanical components outside the Terfenol-D were regarded as a single-degree-of-freedom mass spring damping system, and an equivalent mechanical model of the giant magnetostrictive ultrasonic processing system was addressed. After that, the vibration amplitude was modeled as a function of the frequency and amplitude of the excitation current by considering both magnetization and magnetostriction of Terfenol-D and ultimately achieved through parameter identification using the methods of impedance analysis and nonlinear least-squares fitting. In addition, the relation between resonant frequency of the giant magnetostrictive ultrasonic processing system and the magnitude of the excitation current was studied so that the vibration amplitude model was improved. Thus, the vibration amplitude of the giant magnetostrictive ultrasonic processing system excited by various electric signals with different frequencies and amplitudes can be calculated. As demonstrated by comparison with experimental results, the vibration amplitude model can accurately estimate the vibration amplitude of the giant magnetostrictive ultrasonic processing system. It indicates that the model is meaningful for the design and control of the giant magnetostrictive ultrasonic processing system.
