Gravity Effect on the First Natural Frequency of Offshore Wind Turbine Structures被引量:1
《Transactions of Nanjing University of Aeronautics and Astronautics》2016年第1期95-101,共7页Ma Hongwang Chen Longzhu 
supported by the National Basic Research Program of China(″973″Program)(No.2014CB046200)
The fatigue limit state is critical for most offshore wind turbine.To minimize the development of fatigue damage,dynamic amplification of the response must be avoided.Thus,it is important to ensure that the first natu...
