摘要
用叶型曲线将扭曲变截面风机叶片分割为若干条状区域 ,对每一区域进行三角剖分 ,并将所有的三角平面展开在同一平面上 ,得到叶片的初始展开平面 ,然后用样条曲线逼近该图形的轮廓线 。
Fan blades is firstly decomposed into several strip regions with type line.Each region is then approximated by a number of planar triangles and unfolded into a plane.To have them eliminated the initial pattern is modified by certain deformation.The final shape of the blank is obtained by the approximation of its contour with a spline curve.
