Influence of the Foundation Flexibility on the Vibration Characteristics of the Floating Raft Vibration Isolation System

浮筏隔振系统作为一种有效的减振降噪装置,应用于各种船舶动力系统。为了研究基础的柔性对浮筏隔振系统振动特性的影响,文中提出用多组弹性梁来模拟基础的柔性,设计了具有柔性基础的浮筏隔振试验系统,利用ADAMS软件对该系统进行仿真,研究基础的柔性对隔振系统隔振效果的影响。结果表明,浮筏隔振系统的隔振效果随着基础刚度的增大而提高。

As a kind of effective vibration noise reduction device, floating raft isolation system is widely used in power system of all kinds of ships. In order to study the influence of the foundation flexibility on the vibration characteristics of the floating raft isolation system, this paper proposed a method by using multiple elastic beams to simulate the foundation flexibility. The floating raft isolation system was designed with flexible foundation, and the influences of the foundation flexibility were studied on the vibration characteristics of the floating raft isolation system by using ADAMS software to simulate this system. The results show that the vibration effect of the floating raft isolation system increases with the stiffness of foundation increases.
