摘要随着人类对能源需求的日益增长，围绕能源的争端和矛盾日益突出。寻找新型能源替代化石能源，为人类今后的可持续发展提供无尽的动力，是人类目前面临的重大问题。风能作为无污染的新型绿色可再生能源，受到人类越来越广泛的关注。海上小岛不能与大陆电网直接连通，利用海上风能发电可为海岛居民提供大量可再生清洁能源，海上风能发电已经成为世界各国新能源开发的重要方向。海上风能发电从浅海的桩柱型向深海的浮式发展是必然趋势。近一年来。随着南沙新岛面积的不断扩大，寸土寸金的海岛必须保证人员生活用电和设备用电，否则这样的人造岛礁毫无存在价值，人员无法舒适生存，战备设施无法使用最为致命。保障南海群岛与人造岛礁的正常用电，使得海上风机寿命延长，已经成为急需解决的问题，对于新型深海智能减振的浮式风机来说，其承受水动力与空气动力的双重交变载荷，在其全寿命期内，疲劳载荷循环次数很高，再加上其结构柔性大，工作环境恶劣，在极端海况下动力响应很大，其支撑结构振动尤为明显，极易诱发疲劳破坏。因此，需要特别关注风机平台的振动控制技术研究。61817

 Abstract With the increasing demand for energy, the disputes and conflicts around the energy become more and more prominent. Looking for new energy alternative to fossil energy, to provide endless power for the future sustainable development of mankind, is a major problem facing mankind at present. Wind energy, as a new non polluting renewable energy, has received more and more attention from human beings. Offshore wind power generation from the shallow sea to the deep sea is an inevitable trend in the development of floating type. Over the past year. With the continuous expansion of the area of Nansha Niijima, Cuntucunjin the island must ensure for living and electrical equipment with electrical, otherwise this artificial reefs no existence value, personnel can not comfortable living, readiness facility cannot use the most deadly. Protect the islands in the South China Sea and artificial reefs in the normal use of electricity, the offshore wind turbine service life is prolonged, has become the urgent need to solve the problem, for new deep-sea intelligent vibration of floating wind machine that bear on its hydrodynamic and aerodynamic dual alternating load, in its whole life cycle fatigue load cycles and is high, and its structure is flexible, working environment is bad, in extreme sea conditions dynamic response is very big, and its support structure vibration is particularly evident, easily induced fatigue failure. Therefore, it is needed to pay special attention to the vibration control technology of fan platform..
