极端风况下风力发电机组力学仿真分析
erodynamic simulation and analysis of large wind turbine under extreme wind conditions
风场中的风况变化多端，风力机设计时要考虑到极端风况下的风力机力学性能，在极端风况下风力机处在停机状态，通过流固耦合对风力机进行建模分析，可以得到空气流体的流线、流速、压力等变化情况，同时得到风力机与气流的相互作用力，并分析出风力机的应力、应变，进而对风机经行模态分析，得到其主要阶次的频率和振型。对风力机气动外形设计、预防共振和延长风力机寿命具有指导意义。
Wind conditions change very quickly，at the beginning of design wind turbines, we not only consider aerodynamic property under working condition, but also consider aerodynamic property under halt mode. Under the extreme wind conditions，making an aerodynamic analysis by using the theory of fluid-structure interaction, getting the result of streamline fluid velocity and pressure. We get the stress and strain of the wind turbines by using the force under the interaction between fluid domain and solid domain. And analyzing the frequencies and vibrational modes by modal analysis. It is useful to design the shape and structure, reduce resonance vibration, and prolong life of the wind turbine
