【摘要】 叶片在风电机组中起着关键性的作用,在很大程度上决定了整机的性能。为使风电机组获得最大的气动效率,对动量-叶素理论进行了改进,研究了叶片设计的一般步骤和方法。为满足叶片的气动连续性要求,提出了放射线拟合法来实现叶片表面的光滑过渡。然后依据坐标变换原理将叶片翼型的二维坐标转变为空间三维坐标,最后通过ANSYS软件对叶片进行光滑三维实体建模,为叶片外形的进一步修正及分析奠定了基础。更多还原

【Abstract】 Blade plays a key role in the wind turbines,which determines the performance of the machine to a large extent. This paper studies the Pituitrin-Momentum theory and puts forward the general steps and methods of blade design in order to gain maximum aerodynamic efficiency of wind turbines. To meet the requirements of the blade pneumatic continuity,radiation fitting method is present to realize the smooth transition on the surface of the blade. Then,according to the principle of coordinate change,the coordinates of cross profile are translated from two-dimensional space to three-dimensional space. At last,ANSYS software is carride out on three-dimensional entity modeling through a bottom-up approach. The present paper lays a foundation for further optimization and analysis of the blade.更多还原
