摘要
小型风力发电机组的叶片常年承受动态荷载。为研究其动力特性,以某小型风力发电机组叶片为研究对象,通过叶片振动试验测试其频率和振型,并运用ANSYS有限元分析软件建模分析其模态,有限元结果与试验结果接近。该文的研究可为小型风力发电机组叶片动力特性分析提供参考。
The blades of a small wind turbine are usually subjected to dynamic loads. To study its dynamic characteristics, a blade of a small wind turbine was investigated. The frequencies and modal shapes were measured by blade vibration test and calculated by the finite element software ANSYS. The FE results are close to the test results. This study provides a reference to the analysis of the dynamic characteristics of small wind turbine blades.
