This thesis takes the nonlinear characteristic of the pre-pressing spring into account, the equivalent mechanical model of a Magnetostrictive actuator is set up based on the dynamic experiment of Magnetostrictive material and the influence of unsymmetrical nonlinear rigidity of the pre-pressing spring operating dynamic characteristic of a magnetotrictive actuator is analyzed. By the method of multiple scales we have calculated the unsymmetrical nonlinear question of the pre-pressing spring and obtained the first order harmonic component of a Magnetostrictive actuator and the curve of the pre-pressing spring parameter operating dynamic response to the system. By the numerical simulation, we have found the complicated bifurcation and chaos behavior of the magnetotrictive actuator vibration system.
