ABSTRACT
As such, this paper develops a new vertical-isolation device based on electromagnetic levitation technique. Compared to traditional vertical-isolation devices, the new vertical-isolation device have a favorably capability in active control of vertical vibration. In this study, the configuration department and operational principle of the vertical-isolation device are firstly introduced. Then, the motion equations and control algorithms of isolation system are developed. Finally, the seismic response of a MLIS of typical frame column is numerically analyzed.
