摘要
风力机叶片的动力特性会影响整机的性能,鉴于大型风力机叶片的柔性化特点,采用柔性多体动力学方法来研究大型风机叶片更加符合实际。考虑复合材料叶片各向异性的特点,通过ANSYS和ADAMS软件建立了750 kW风机叶片的柔性体模型及风轮的刚柔混合体模型,利用载荷的文档输入法将BLADED计算的风力机载荷生成曲线并加载到风机上,对风轮进行动力学仿真分析。结果得到了风机叶片的动态特性数据,并与刚性体叶片特性进行对比,这将有助于风机整机动态特性的研究,也为大型风机叶片的故障分析、优化设计提供参考。
In view of flexible characteristics and the importance of blades,it is suited to use flexible multibody dynamics method to study them.Considering the anisotropic composite blades,this paper establishes the rigid-flexible wind rotor model of the 750kW wind turbine by the software of ANSYS and ADAMS.And the loads which are computed by BLADE are loaded on the rotor to analyze the dynamic characteristics of the blades.The dynamic features of the flexible and rigid blades are obtained.It also makes a study of WTGS by comparison with both characteristics of the blades,and gives a reference data to blade trouble analysis and optimization design.
