| Abstract: | Using the finite element method, the static characteristic, the natural vibration characteristic, the vibration isolating characteristic and the anti-shock characteristic of an onboard floating raft are studied in this paper. Then the vibration isolating characteristic of the floating raft is tested. The acceleration level difference of the floating raft is more than 35dB. The experimental results show that the simulating results are reliable. The simulating method used in the analysis can be a significant guidance in the design of onboard floating raft vibration isolating equipments. |
