摘要
理论上相贯线是由无数个点组成的,采用手工制图时只能选取有数的几个相贯点,然后连成线。这样形成的相贯线精度差、效率低,难以满足实际生产要求。应用解析几何的方法详细推导了两个相交圆管的相贯线的数学模型。依据此模型,再结合计算机技术,即可精确求解相贯线。
Theoretically, an intersecting line is composed of numberless points. In a manual drawing, only a few intersecting points are taken to connect into a line which is, inevitably, low in both precision and efficiency, and falls short of demands in practice. This thesis has come up with an elaborate mathematical model which is derived, by adopting the principles of analytical geometry, from the intersecting line of two intersecting round tubes. The model, aided with computer technology, can provide a precise solution to the problem of intersecting line.
