摘要:利用Profili翼型软件和UG获得了2.0MW风力发电机叶片的三维模型,并将叶片模型导入ANSYS Workbench进行流固耦合分析,得到叶片在流场中应力、应变和变形等有限元分析结果。通过结果分析,得出叶片最大应力在叶根处附近,最大变形量发生在叶尖处,叶片在流固耦合条件下,其主要变形集中在靠近叶梢的中上部,且越向叶梢变形越大,并成非线性分布。这些分析结果为叶片的优化设计及研发工作提供了相关数据,从而减少了产品开发周期,降低了开发成本。

Abstract:Using airfoil profile software and UG software,the 3D model of 2.0 MW wind turbine blade is obtained, the fluid-solid coupling Analysis of 2.0 MW wind turbine blade is carried out by ANSYS Workbench, and the stress, strain and deformation results of blades are obtained. By analyzing the results, it is concluded that the maximum stress of blade appears near the blade root, the maximum deformation appears at the blade tip. Under the condition of fluid-solid, the main deformation concentrates in near the upper of the blade tip, and the deformation of blade tip is bigger and bigger. These analysis results can provide the related data for blade optimization design and research, thereby reducing the product research cycle and the cost of development.
Key words:2.0MW;wind turbine blade;fluid-solid coupling analysis;ANSYS Workbench
