随着海上风机单机容量朝着大型化发展，为适用DTU 10 MW风机，本文基于OC4浮式基础设计建立四浮筒基础。通过AQWA建立水动力计算模型，以三维势流理论对该浮式基础进行频域内的运动响应仿真计算，并对四浮筒基础的水动力性能进行分析。得出结论：该基础具有良好的对称性，在低频区域波浪入射角度和水深对浮式基础的运动响应影响明显，高频区域响应相对较小，水动力性能良好。分析结果可为后续海上风机四浮筒基础设计提供一定的参考。
With the deep-water development of offshore wind turbine and the large-scale development of single wind turbine capacity, in order to apply DTU 10 MW offshore wind turbine, this paper establishes four pontoon foundation based on OC4 floating foundation of offshore wind turbine design. In this paper, the hydrodynamic calculation model is established by AQWA software, the motion response of the floating foundation in frequency domain is simulated by three-dimensional potential flow theory, and the hydrodynamic performance of four pontoon foundation is analyzed. It is concluded that the foundation of offshore wind turbine has good symmetry, the wave incidence angle and water depth have an obvious influence on the motion response of the floating foundation in the low-frequency region, the response in the high-frequency region is relatively small, and the hydrodynamic performance is great. The analysis results can provide some reference for the follow-up design of four pontoon foundation of offshore wind turbine.
