Witness Test of Oil Dampers for Taichung Treasure Garden TMD took place on May 10th, 2016, at ITT Enidine, Buffalo. Mr. Huang from CEC, Mr. Yao from Evergreen, and Mr. Sung from MIC joined us from Taiwan.
Special thanks to ITT Enidine members that has greeted us with open arms and shown their professionalism and capabilities throughout the testing process.
Research on vibration reduction of wind turbine tower has been successfully completed at TESolution structural lab. The wind turbine towers are generally greatly exposed to vibrations not only from wind but also from the turning moment of the turbine. Such vibrations can cause number of problems on the structure, including malfunction of the generator and structural instability of the tower. A pendulum type TMD(Tuned Mass Damper) with silicon oil damper was designed to be installed inside to reduce the vibration. The result showed reduction of the vibration with over 30%.
< TMD Specification for 3 Mega Watt Wind Turbine >
- Natural Frequency of tower = 0.3616Hz
- TMD MASS= 5ton
- Damping Ratio= 12.8%
< TMD Specification for 7 Mega Watt Wind Turbine>
- Natural Frequency of tower = 0.2874Hz
- TMD MASS= 13ton
- Damping Ratio= 10.6%
In April, dismantle of TMD mass of Dubai Structure has been conducted. The dismantle process was conducted safely by site workers in Abu Dhabi. The dismantled mass shall be reinstalled, once all the parts have been transported to Dubai site. Thank you to all those involved in the process.
