双层浮筏隔振系统筏体结构与隔振特性的研究

Research on Raft Structure and Isolation Characteristics of Double-decked Floating Raft Isolation System

双层浮筏隔振系统中，筏体结构对隔振效果的影响重大，针对不同的筏体结构，在MSC／PATRAN中建立了浮筏的有限元模型，并且分析其固有振动特性、隔振效果，为隔振设计提供参考。

The raft structure has a significant effect on the vibration isolation in Double-decked floating raft isolation system.In view of the different raft structure,the finite element model of raft has been established,and the natural vibration characteristic and isolation effect are calculated using MSC/PATRAN.
