基于三维激光扫描的风电机组叶片重构建模应用研究

Research on wind turbine blade reconstruction modeling based on 3D laser scanning

随着早期风电场对叶片增效技术需求的增加,叶片原始数据的获取越来越重要。本文采用逆向建模工程方法,创新性提出“三维激光扫描气动外形+切割测量铺层结构”的方法,逆向重构了某一600kW机组叶片的气动布局及结构。验证结果表明,逆向建模叶片的质量、机组功率曲线及关键载荷与原始机组设计值偏差极小,验证了该方法的有效性,为风机叶片增效技术缺乏数据提供了新的解决思路。

With the increasing demand for blade efficiency technology in early wind farms,the acquisition of blade raw data is becoming more and more important.In this paper,we adopt the reverse modeling engineering method and innovatively propose the method of"3D laser scanning aerodynamic shape+cutting measurement of layup structure"to reverse reconstruct the aerodynamic layout and structure of a 600kW unit blade.The verification results show that the quality of the reverse modeled blade,the power curve of the unit and the key load deviate very little from the original unit design value,which verifies the effectiveness of the method and provides a new solution to the lack of data for wind turbine blade efficiency technology.
