| Abstract: | A generalized theoretical model of floating raft vibration isolation system is proposed. The corresponding structural analysis method is developed to predict the dynamic characteristics, and the transfer equations are derived. Based on the above, numerical calculations of power flow for practical floating raft isolation system are carried out to explore the interactions between mounting frequency and the flexibility of supporting structure, and the effects on power flow are discussed. It is shown that the power flow can be reduced effectively by reasonable choice of design point for mounting frequency. |
