An Investigation of the Anti-shock Property of the Floating Raft Installation for Vibration Isolation

The investigation on the anti-shock property of the floating raft installation was made both theoretically and experimentally.The Expressions of the shock acceleration of the equipment as well as the deformation of the isolator were deduced on the basis of the setting up of the mechanical model of the isolation system.Through the tests on the floating raft model，the response of the device was surveyed.Then the influences of the frequency ratio as well as the mass ratio on the anti-shock property was discussed.
