摘要
针对3MW水平轴风力机,为了探究多载荷共同作用对风力机结构部件的影响效果,本文利用GH Bladed对3.2MW风力机进行仿真计算,通过探究气动载荷和地震作用对风力机结构受力特性的影响,证明了在风力机载荷计算中考虑地震作用的必要性。结果表明,当载荷共同作用时,结构载荷随着地震动加速度值增大而增大,说明结构载荷与地震动加速度值之间呈正相关性;相较于稳态风,湍流风变化的波动性会使结构的承受载荷增大。相关研究成果为风力机的结构优化设计和安全运行提供数据参考。
For 3MW horizontal axis wind turbine,in order to explore the effect of multi-loads on wind turbine structural components,this paper used GH Bladed to conduct simulation calculation for 3.2MW wind turbine,and proved the necessity of considering seismic action in wind turbine load calculation by exploring the influence of aerodynamic load and seismic action on wind turbine structure stress characteristics.The results show that the structural load increases with the increase of the ground motion acceleration when the load is coupled,which indicates that the structural load is positively correlated with the ground motion acceleration.Compared with steady wind,the fluctuation of turbulent wind will increase the load of the structure.Relevant research results provide data reference for structural optimization design and safe operation of wind turbines.
