    摘要:

    针对复合材料网格结构筋条及蒙皮缠绕成型的需求,运用微分几何方法,对柱圆锥面螺旋线短程线进行了探讨。解决了复合材料网格结构筋条及蒙皮的缠绕成型问题。结果表明圆柱和锥段螺旋线的弧长和曲率计算方法,可用于圆柱段和圆锥段复合材料网格结构成型装置的设计生产和纤维缠绕。对数螺线和阿基米德螺线的弧长和曲率计算方法,可用于锥段复合材料网格结构软模成型装置的设计生产和纤维缠绕,为复合材料网格结构自动化制造创造了条件,同时针对工程需要,对不同的网格结构选择不同的加工成型方式,可大大降低加工难度,实现低成本快速批量生产。

    Abstract:

    According to the demand of the gird structure skin and rib texture winding formantion,this article discuss the spiral curve and geodesic line of column and cone by means of the differential geometry method. The problem of the composite grid structure skin and rib texture winding formation was solved. The results show that the arc length and curvature calculation method of the spiral curve and geodesic line of column and cone can be used for the design and manufacture of the mold forming device of the composite grid structure and fiber winding.The calculation method of arc length and curvature of logarithmic spiral and archimedes spiral can be used for the design and production of the soft mold forming device of the cone composite grid structure and fiber winding.The condition for the automation manufacture of the composite trellis structure has created.At the same time, for engineering needs, different kinds of grid structure are selected for different processing and forming methods, which can greatly reduce the processing difficulty and realize low cost and fast mass production.
