The Finite Element Design of Air Compressors Floating Raft Impact Vibration Isolation System on Ships

A finite element model of floating raft vibration isolation system are established in this paper. The stress cloud and the natural frequencies are given based on the analysis of the static response and modes of this floating raft vibration isolation system. The calculation and analysis above may be helpful for preventing the floating raft system from working on resonant area and for keeping the oversize dynamic deformation. On this basis, vibration isolation effect has been assessed by vibration level difference
