摘要
根据风力发电机组叶片的结构特点,在三次样条插值函数拟合叶片翼型曲线的基础上,提出一种利用计算机建立叶片截面与三维模型的程序设计方法.该方法应用插值拟合理论求解叶片截面翼型曲线离散点的坐标,应用点的坐标变换理论求解各离散点空间实际位置的坐标,应用三维几何建模理论建立叶片模型.最后给出一个仿真实例.
According to the structural features of wind turbine blades, and on the basis of blade aerofoil curve fitted with triple spline interpolation function, a kind of interpolating fit theory. Secondly, the data of the airfoil of blades are revolved and convered to form the data of the 3D-block body of blades on the ground of coordinate conversion. Lastly, the 3D model is drawn based on the 3D theory.
