ElectroMagnetic Vibration isolation and stabilization system theory and simulation
MetadataShow full item record
Vibration isolation is undoubtedly one of the most efficient methods of Structural Control. The ElectroMagnetic Vibration Isolation and Stabilization System (EMVISS) proposed here is the very first vibration isolation that could provide six Degrees-of-Freedom (DOF) vibration isolation. In this dissertation, after discussion on the conventional vibration isolation systems (for both seismic and non-seismic applications) and current electromagnetic actuation systems, development of EMVISS will be discussed in detail. Finding a configuration that results in satisfying results, understanding the mechanical and electromagnetic dynamics of the system, and designing appropriate controllers for different modes of EMVISS are explained in detail. The proposed system could function on very reasonably sized batteries and this independency from the grid is an important advantage. The performance of the proposed system is evaluated using different series of hybrid simulations. The promising results obtained from these thorough simulations could possibly bring a new generation of active structural control methods for seismic protection of nonstructural components (NSC), specific parts of structures, or the structure as a whole. Application of EMVISS could also easily be extended to non-seismic vibration control.
