摘要
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.
