为在研究大型风力机气动性能的同时考虑其结构动力学特性，基于开源计算流体力学软件OpenFOAM及气动-水动-伺服-控制软件FAST，并结合致动线方法（Actuator Line Method,ALM）实现风力机叶轮周围流场信息与结构响应间的数据交换，最终完成风力机气动-结构仿真平台FASTFOAM构建。通过该平台计算了风场中两台串列布置5 MW风力机的气动性能及结构动力学特性。结果表明：FASTFOAM平台能够快速计算出风力机的功率输出、结构响应及流场信息；风力机尾迹在发展过程中可持续与周围流场进行能量交换而使其速度亏损得以弥补；下游风力机受上游风力机尾迹影响严重，输出功率只有上游风力机的21.05%，且结构动力学响应与上游风力机不同；上游风力机和下游风力机叶轮的主要刺激频率分别为0.16和0.15 Hz。

In order to study the aerodynamic performance of large wind turbines and consider their structural dynamic characteristics simultaneously,the open source computational fluid dynamics software OpenFOAM and aerodynamicshydrodynamicsservocontrol software FAST,along with actuator line method (ALM),were combined to realize the exchange of data between flow field information around the rotor and its structural response.Finally,the construction of wind turbine aerodynamicstructural simulation platform in FASTFOAM was completed.The aerodynamic performance and structural dynamic characteristics of two 5 MW wind turbines arranged in tandem in the wind farm were calculated by this platform.The results show that the FASTFOAM platform can quickly simulate the output power,structure dynamic responses and flow field information of wind turbines.Wind turbine wake can sustainably exchange energy with the surrounding flow field during its development process to compensate for its speed deficit.The downstream wind turbine is influenced seriously by the wake of the upstream one,and its output power only accounts for 21.05% of the upstream wind turbine and its structural dynamic characteristics are different from the upstream one.The main stimulation frequency of the upstream and downstream wind turbine rotors is 0.16 Hz and 0.15 Hz,respectively.
