  • Through analyzing the constitutive relation of the giant magnetostrictive material, the main controllable factor constituting the output displacement for giant magntostrictive actuator was discussed. Upon which to investigate the key factors of single layer and one degree of freedom isolation platform based on giant magntostrictive actuator, a model with the displacement responding to acting force of the platform as its reference input was presented. Through analyzing the vibration isolation principle with the model, the conclusion was drawn that both acting force frequency and the maximum displacement of actuator are crucial to the effect of the system, in that the system vibration isolation capacity is direct ratio to the square of acting force frequency and maximum displacement of actuator. In time-domain, simulations based on Matlab platform with adaptive LMS (least mean square) algorithm were carried out to verify the conclusion. Thus it is theoretically instructive to design a vibration isolation system with giant magnetostrictive actuator, and the model is suitable to the system with giant magnetostrictive actuators as well to the system with other kinds of actuators.
