The Dynamic Characteristics of the Controllable Floating Raft System

Abstract

In this paper, the dynamic characteristics of some controllable floating raft test system are studied. The virtual dynamic model of the system is established in Adams, the acceleration responses of system in different damping states are simulated, and the vibration level differences of system in different damping states are contrasted. The results show that it is able to improve the vibration isolation property in wide frequency range by switch on-off control of the controllable damper. Finally the possibility to improve the vibration isolation property of system by semi-active control of variable damper is discussed.
