Research on the Transmission Characteristic of Magnetic Floating Raft Isolation System

A magnetic suspended isolator was designed and paralleled with some passive ones.They were applied in the floating raft vibration isolation system.Then,the dynamics model of the system was established.The simulated transmissibility curves of magnetic suspended floating raft isolation system with different stiffness were achieved by Adams software.The simulation results showed that the floating raft isolation system with magnetic suspended isolators could remarkably suppress vibration in the wide range of frequency and were more effective in vibration isolation in comparison with the passive isolation system.
