| 摘 要： | 通过控制叶片的行为模拟风机故障状态，采用广义动态尾迹理论获得叶片的气动力载荷并将其加载到风机支撑结构顶部，最后获得故障情况下风机支撑结构危险截面的等效应力、弯曲应力和塔顶的位移等时程曲线。分析结果显示，风机故障情况将在短时间内急剧增大结构的动力响应。研究表明，应尽量减小故障情况对支撑结构造成的载荷影响，避免结构破坏。

| Abstract: | The dynamic response of supporing structure of an offshore wind turbine under diagnosis state was studied. The time-history curves of equivalent stress, bending stress and tower top displacement were gained for the supporting structure via controlling the behavior of blades to simulate wind turbine＇s fault condition. Numerical results showed that a sharp increase of the response of structure under diagnosis state within a short time frame. So, the impact of the response on the supporting structure due to fault condition needs to be minimized to avoid being destroyed. |
