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)浮筏中间筏架的质量 (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。
In this paper, the model of floating raft vibration isolation system is modeled by the finite element super-element reduction model. The quality of the raft raft (especially when the mass ratio is relatively small) is discussed through the analysis and calculation. (2) (Especially when the stiffness of the raft is small); (3) the structural damping of the raft and the damping of the damper in the device; and their influence on the vibration isolation performance of the whole raft, some useful conclusions are drawn .
