    • 本研究探討離岸風機支撐結構行為受風浪載重之影響。本研究將分為三個部分，第一部分為波浪載重之計算模組，由規範(DNV-RP-C205)建議公式計算波浪載重，其中包括了Morison equation用來計算流體通過細長圓形桿件之作用力、Airy wave theory 和 Stokes second-order theory用來建構波浪流動之運動特性。第二部分為風力載重之計算模組，風力載重利用美國國家再生能源實驗室(NREL)所開發之分析軟體FAST及TurbSim來計算風作用於風力發電機上之外力。第三部分，將波浪模組和風力模組之載重計算結果輸入到離岸風機支撐結構網格製造程式中(WINDTURB)，再由有限元素分析程式(AN)作為平台進行結構分析。最後設計範例進行分析和討論離岸風機支持結構受波浪載重及風載重之行為。研究成果及結構分析程式是由 朱聖浩教授研究團隊所開發，所有軟體都為公開資源，任何人、任何機構均可無償使用。

    This study investigates the dynamic behavior of offshore wind turbine support structures under wave and wind loads. This study is divided into three parts. The first part is the calculation module of wave loads according to the standards (DNV-RP-C205), where the Morison equation is included to calculate the wave loads on circular cylinder members, and the Airy wave theory and the Stokes second-order theory are used to describe the wave kinematics. The second part is the calculation module of wind loads, while the wind loading is calculated by programs TurbSim and FAST which were developed by NREL (National Renewable Energy Laboratory). For the last part, the loading calculated by the modules of the wave and wind will be added into the finite element mesh using a mesh generation program (WINDTURB) for the offshore wind turbine support structures. Finite element analysis program AN is thus used to perform the structural analysis. Then, the analysis and discussion of the behavior of offshore wind turbine support structures under wave and wind loads. It is noted that the computer programs developed by the research group of Shen-Haw Ju are open sources and free to be used.
