摘　　要：为研究海上风力机在不同环境载荷下的结构动力学特性,基于5 MW海上风电力机,采用Kaimal风速谱建立平均风速为12 m/s的湍流三维风场,在一体化分析软件OpenFAST中分别计算不同工况下海上风力机的动力学特性。仿真结果表明:在风、冰联合作用的工况下,风力机塔基横向、纵向的弯矩位移均大于单一载荷作用工况下的塔基位移。风力机纵向弯矩主要受到湍流风作用,使用DNV方法得到的风力机疲劳损伤值大于风、冰联合作用工况下的计算结果,以海上风力机结构动力响应为评价指标,对该结果的有效性进行了验证。In order to study the structural dynamics of offshore wind turbines under different environmental loads,a turbulent three-dimensional wind field with an average wind speed of 12 m/s is established based on a 5MW offshore wind turbine using the Kaimal wind speed spectrum,and the dynamics of the offshore wind turbine under different working conditions are calculated in the integrated analysis software OpenFAST.The simulation results show that the transverse and longitudinal moment displacements of the tower base of the wind turbine are larger than those of the tower base under the single-loading condition under the combined wind and ice conditions.The lateral displacement of the platform is much larger than the longitudinal displacement of the platform,and the longitudinal bending moment of the wind turbine is mainly affected by the turbulent wind.The fatigue damage values obtained by the superposition calculation of the DNV method are larger than the results obtained by the combined wind and ice action.
