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