| 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.

| Abstract: | 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 program design method is offered to display the section and 3D model of wind turbine blades.Firstly,the data of the airfoil of blades section are revolved based on the 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. |
