用于模拟试验条件下风机等效推力的推进器布局设计方法

By using MATLAB optimization algorithms and Euler angles to determine the thruster installation position, combined with a motion capture system and OpenFAST software, the accuracy problem of wind turbine thrust simulation in traditional scaled-down models was solved. This achieved high-precision equivalent simulation of wind turbine loads and structural consistency, thus improving the reliability of floating wind power model tests.

Abstract

本发明属于海洋风电技术，公开了一种用于模拟试验条件下风机等效推力的推进器布局设计方法，对叶片、桨毂、机舱及塔筒质量、质心和转动惯量进行统一匹配设计，保证缩比模型在重力特性方面与原型结构保持一致，塔筒振动频率得到准确复现；建立推进器推力至塔基六自由度荷载的统一映射模型，适用于不同数量、不同空间构型及不同安装方向的推进器布局设计，突破传统经验式布置方法的局限；构建塔基目标荷载与推进器合成荷载之间的映射关系，可同时准确模拟风机荷载效应，且大尺度结构的柔性特性也于数值方法中考虑，有效提高了风机气动‑弹性载荷缩比模拟精度。该方法能够综合考虑塔筒振动频率、结构柔性效应以及风机质量属性匹配要求。
