钢岔管结构的计算机辅助几何设计

CAGD OF STEEL BRANCH PIPE CONSTITUTION

钢岔管是管道工程中常见的结构．作者利用空间解析几何的方法建立其数学模型，并对其进行计算机辅助几何设计（ＣＡＧＤ），为钢岔管的设计、制作提供图形、数据及设计的方法．

A steel branch pipe is a common constitution in pipeline engineering. By making use of space analytic geometry, the mathematic model of steel branch is created, and computer aided geometry design (CAGD) is carried out in this paper. This paper provides the graph, data and method for the design and manufature of steel branch pipe as well.
