Modeling and Analysis of the Active Vibration Isolation with Giant Magnetostrictive Actuator

A novel reformulation of a classical active vibration isolation problem is described, aiming at deducing a system vibration isolation capability function with the acting force frequency and maximum displacement of actuator as variables. By utilizing a reformulation of the problem rather than the traditional approaches, the crucial facts affecting the performance of the system are found out. A model with the displacement induced by the acting force of the platform as its reference input is presented. Through frequency domain analysis, it can be found that the system vibration isolation capability is direct ratio to the square of the acting force frequency and maximum displacement of the actuator. Furthermore, a numeric simulation is carried out to validate the perspective.
