| 摘 要： | 以NREL 5 MW近海风力机为研究对象,基于Kaimal平稳随机风速谱模型建立风力机全域湍流风,同时采用Matlock模型计算动态冰力,模拟风力机所受冰激振动,研究在风-冰联合环境载荷作用下近海风力机动力学响应。结果表明:冰激振动极大地加剧塔顶各向振动;频域上,冰激振动影响主要集中于塔架1阶固有频率和叶片1阶摆振频率,且相应峰值与冰厚呈正相关关系;受冰激振动作用,塔架各向剪切力明显增加,且塔顶和塔基附近增幅大于塔身中部。

| Abstract: | The paper presents the numerical simulation for the offshore wind turbine suffering the aerodynamic load and floating ice load simultaneously.The NREL 5 MW offshore wind turbine is adopted in this study.The Kaimal stationary random wind spectrum is used to establish the turbulent wind for aerodynamic load calculation.The Matlock model is used for computing the dynamic ice force and simulating the ice induced vibration on the offshore wind turbine.The results show that: the ice induced vibration intensifies the oscillation of the tower.The 1st natural frequency of tower and the 1st flapwise natural frequency are impacted by the ice induced vibration most significantly and the amplitudes near these frequencies increase with the ice thickness.The shear forces on the tower are increased by the ice-induced vibration,with the increments for top and bottom of tower larger than the middle of tower. |
