球面封头圆管插件展开CAD

CAD on the Development of Cylindrical Branch of Pipes on Ellipsoidal Surface

推导了球面封头与圆柱形插件斜交相贯线上各点坐标求解公式 ,给出了作插件展开图所需的素线实长公式 ,介绍了根据以上公式编写插件展开图的步骤及用到的其他相关公式 ,最后给出了一个应用实例。

In this paper, the formulas of the intersection on cylindrical branch of pipes on ellipsoidal surface is derived. The formula of real length that is needed during drawing is given. The steps of design program for drawing the developmental figure and relation equations are introduced too. Finally, a practical example is given.
