Abstract

Floating raft vibration isolator (FRVI) is widely used in ship system. This study investigated effects of FRVI parameters on the overall performance of vibration isolation. Mechanical model of FRVI was established. Using the theory of admittance transmission power flow was deduced. The influence of FRVI transmission power flow by the weight of the raft frame, the thickness of the base and the bearing stiffness of the system was analyzed. The transmitted power flow curve was simulated by computer. In analysis found that the bigger the quality of the middle raft, the better for the performance of the system under actual conditions permit. In the condition of not affecting the stability of the system, the smaller the support rigidity of the system, the better for the system. The thickness of the infrastructure, the bigger, the better. A theoretical basis was provided for the design of intermediate weight, the foundation and the bearing stiffness of the system of FRVI.
