Analysis of Hysteretic Property of Giant Magnetostrictive Actuator
In this article, the composite nonlinear mathematic model, based on the hysteretic theory of the giant magnetostrictive material (GMM) and the nonlinear characteristic of the giant magnetostrictive actuator (GMA), is established with Bouc-Wen hysteretic model, and the hysteresis properties are investigated. Then with Multi-scale method, the analytic solution of the response and the expression of the frequency-response properties, which the giant magnetostrictive actuator with hysteretic and geometric nonlinear vibration characteristic includes, are achieved, and the t-x curve is obtained. Then, after the discussing about the different cases, the frequency-response curves are obtained with damp case and without damp case, and the affect of frequency-response characteristic with damp expressed by the dynamic excitation f, piezomagnetic coefficient d33 and magnetic conductivity μ33 T to the curve of the frequency-response is discussed. Results indicate that the affect of f, d33 and μ33 T to the amplitude and nonlinear of the system is obvious. At the same time, the frequency-response curve has the phenomenon of double hopping.
