Active control and simulation of isolation platform with high accuracy

The dynamical analysis and computer simulation of the isolation platform controlled by electromagnetic forces with high accuracy are carried out. The vibration environment included basement vibration, periodical variation of tide generating force of the sun and the moon, movment of test equipment on platform and other transient shock. According to simulation results, the effects of the variation of mass, stiffness and damping of the platform system on active isolation or passive isolation are analyzed, and the effects of the variation of parameters in active control on vibration isolation are also analyzed.
