海上浮式风机张力腿平台的水动力响应

Hydrodynamic response of a floating offshore wind turbine tension leg platform

以美国某可再生能源所的海上5 MV风机为模型,结合风机塔柱的特点,利用Orca Flex建立了一种海上风机张力腿平台简化模型。通过时域耦合计算方法和傅里叶变换,得到了该系统的动力学响应,对比并分析了在考虑涡激振动和不考虑涡激振动时各个张力腿的动力学变化和平台的水动力响应。

Based on the 5 MV wind turbine of a certain renewable energy institute in America and reference to the characteristics of the wind turbine tower, the model of a floating offshore wind turbine tension leg platform was established by OrcaFlex. By the time domain coupled calculation method and Fourier transform, the dynamic re- sponse of the wind turbine tension leg platform was researched. The hydrodynamic response of the system under the action of the vortex induced vibration was analyzed, and the results were compared to that without the action of the vortex induced vibration.
