| 摘 要： | 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。

| Abstract: | The geometric property of natural path on developable surface is analyzed,and it is proved that the natural path and the geodesic line is equivalent on the developable surface.By application and modification of the natural path calculating method on developable surface,a new approach for calculating natural path on general surface is developed,in which new control points are induced to adjust center point of prepreg tape so as to decrease its global deformation. |
