中文摘要: |
提出了一种框架型浮筏隔振系统,通过三维软件对浮筏系统进行建模,利用ANSYS分析软件对框架浮筏隔振系统进行谐响应分析,求得系统在外力作用下的振动情况,再以功率流方法分析浮筏系统的隔振效果。得出框架浮筏系统的隔振效果较为理想,特别是当激励处于在高频段时。 |
英文摘要: |
A kind of frame floating raft system was proposed and its building model was proceeded with a three dimensional software. The vibration module of frame floating raft and harmonic response of the model were analyzed by ANSYS to obtain the vibration situation of the system under the outerforce action. Based on the analysis the isolation efficiency of the floating raft system was evaluated by power flow method. The results showed that the isolation effect of the frame floating raft system is excellent, especially when the excitation is in high frequency section. |
