In the present study, the chaotic response of the nonlinear magnetostrictive actuator (GMA) vibration system is investigated. The\nmathematical model of the nonlinear GMA vibration system is established according to J-A hysteresis nonlinear model, quadratic\ndomain rotation model, Newtonâ??s third law, and principle of GMA structural dynamics by analyzing the working principle of\nGMA........................
