分析了可展面上“自然路径”的几何本质,推演证明其在可展曲面上与测地线的等价性。应用和拓展可展面“自然路径”数值算法,在一般曲面上引入边界控制点调整预浸带中心点以减小预浸带变形、实现铺放,构造了一般曲面“自然路径”求解格式。
The geometrical nature of the “natural path” on the exhibition surface is analyzed, and its equivalence to the geodesic is proved. By applying and expanding the numerical method of the “natural path”, a boundary point is introduced on the general surface to adjust the center point of prepreg to reduce the deformation of prepreg strip.
