| 摘 要： | 本文运用有限元超单元降阶模型对浮筏隔振系统进行建模，通过分析计算探讨了（１）浮筏中间筏架的持呈（尤其是质量比较小时）；（２）浮筏中间筏架的刚度（尤其是筏架刚度较小时）；（３）浮筏中间筏架的结构阻尼和装置中的阻尼器的阻尼；它们对整个浮筏隔振性能的影响，从中得出一些有益的结论。

| Abstract: | Thereduced finite element model of the floating raft isolation system is established toinvestigate the influence of different parameters,including(1)mass of raftframe,especially for the little mass raft frame;(2)stiffness of raft frame,especially forthe low stiffness raft frame;(3)damping of the raft frame and kind of dampers,on theisolation characteristics of the floating raft isolation system.The results are of benefitto the design of a real floating raft isolation system. |
