This system uses air springs as passive vibration isolation elements and giant magnetostrictive actuators as active vibration isolation elements.

Four vertical actuators and air springs are set in parallel to make use of the giant magnetostrictive actuators effectively.

The giant magnetostrictive actuator is characterized by large displacement, high force, fast response, high reliability, small amount of drift and low voltage drives and so on and has a wide range of potential applications in super-precision positioning, micro-motor, vibration control and fluid machinery, etc.

A dynamics model and ANSYS model is proposed to improve the design efficiency of a giant magnetostrictive actuator (GMA), and calculation and simulation of its axial resonant frequency are performed.
