摘要/Abstract

摘要： 针对某一现有2 MW风力机叶片,分析其叶根几何形状及铺层结构,并设定叶根连接各金属件几何尺寸,通过MATLAB编程并结合ANSYS二次开发建立风力机叶片叶根连接参数化几何模型,同时自动进行材料属性设置、网格划分及接触设置。基于GL 2010标准载荷计算结果,提炼出叶根极限载荷工况,同时在最大叶根螺栓预紧力工况下,按载荷步自动对模型进行非线性求解,从而得到极限载荷下的螺栓载荷因子。通过VDI 2230对叶片叶根螺栓进行静强度校核,同时考虑钻孔区域的应力集中效应,对叶根复合材料部分的静强度进行校核分析,校核结果表明,该叶根连接设计能够满足极限载荷条件。该研究全面分析了叶根连接各部件的静态性能,并为后续叶片叶根连接的设计优化奠定了基础。

Abstract: In view of the existing 2 MW wind turbine blade, the geometry structure and layer condition, were analyzed. The geometry dimension of every metal part connected with the blade root was set, the parameterized geometric model of wind turbine blade root connection was found through MATLAB and ANSYS secondary development, and material properties, grid mesh and contact pairs were set automatically. Based on GL 2010 standard load calculation results, the ultimate load condition of blade root was extracted, the nonlinear solution of the model was carried out according to the load step automatically under the maximum pretension force of bolt, and the load factor of bolt is obtained. The static strength of blade root bolt was validated according to VDI 2230 standard, the stress concentration effect in the drilling area was considered, the static strength of the composite material part of the blade root was validated and analyzed. The results show that the design of blade root connection could meet the ultimate load condition. The research analyzes the static performances of blade root connection every component comprehensively, which lays the foundation for the design of blade root connection to be optimized further.
