| 摘 要： | 针对船用浮筏隔振系统,基于有限元法建立了一种浮筏隔振系统的有限元模型,采用振级落差方法估算了浮筏隔振系统的隔振效果,并与试验结果进行了对比,振级落差理论估算与实测值基本一致,在一定精度范围内能满足工程要求.

| Abstract: | Aiming at the marine floating raft isolation system, Finite Element Method (FEM) model of floating raft isolation system are set up in this paper. The Vibration Level Difference is applied to measure the effect of vibration isolating. Compare the experiment result with theoretic value. It shows that this method would fulfill the need of the ecumenical isolator engineering design. |
