    椭圆形封头的展开方法

    Development of ellipsoidal envelope

    • 摘要: 用测地线与法截线相结合的方法,提出椭圆型封头曲面的展开模式,并建立了数学模型,为用计算机展开椭圆型封头曲面提供了途径。可以提高展开效率和精度,并使这种方法与JB1154-73标准相匹配。

       

      Abstract: This paper tries to express an approximate development model of ellipsoidal envelope using the method in combining geodesic line with normal cut line. To obtain the optimum effect, a corresponding mathematical model for the use of computer-aided development is so established. This method matches standard JB1154-73 well.
