The Dynamic Performance Improvement and Vibration Suppression with Turned Liquid Column Dampers to the Tension Leg Platform / 大型浮式海域平台受波浪作用之動力行為減振研究

碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 92 / In this study, a tension leg platform (TLP) incorporated with the TLCD (Tuned liquid column damper) is tested experimentally. The advantages of TLP with TLCD devices are as follows:1.When the TLCD devices use on the TLP, the columns under the platform could provide the buoyant force. 2. When the TLCD devices are injected into water, the vibration of the platform could be mitigated by the water sloshing power. 3. It can change the natural frequency within limits by changing the liquid length.
In this thesis, a scaled-down model is tested in the laboratory to verify the analytical results. When the experiment tested, the total mass of the system should be the same no matter if the TLCD devices are applied or not. We used the accelerometers to obtained the acceleration of the platform including the surge, heave and pitch motions. The tendon force is obtained by the strain gage.
Can be found from the experiment course, after the structure adds the TLCD devices, the responses of three motion can be effective reduced. So what reducing shaking to disappear and can be designed and discussed best by this text under various kinds of situations of finding out.
