| Abstract: | In this paper,a generalized theoretical model of floating raft vibration isolation system is presented,and the corresponding structral analysis method is developed to predict the power flow characteristics.Being based on the above,numerical calculation of the transmitted power flow for practical floating raft coupled system is performed to explore the effects of mount frequency and isolator damping on the flexibility of supporting structure and transmitted power flow within the ovweall system. |
