摘要: 为构造共轭曲面计算机处理系统,提出共轭曲面自适应综合的离散解析原理。从共轭曲面的创成过程出发,将母曲面∑2和创成曲面∑1看作两簇空间网格点集,认为∑1是由运动过程中∑2上满足共轭条件的点在S1坐标空间中的宏观表现,通过微分几何中共轭条件的等价变换在数学模型上将计算机运算和共轭曲面解析求解结合起来。离散解析原理不仅能处理解析的共轭曲面问题,而且能处理离散的共轭曲面问题,达到共轭曲面综合的智能化、自动化。

Abstract: The discretization and analysis principle of conjugating surfaces for adaptive synthesis is proposed in order to construct computer software of conjugating surfaces. Taking the generating process of conjugating surfaces into account, the surface∑1, and the surface∑2 are regarded as two point sets, and the surface∑1, is regarded as the whole image of vestiges of the points, which satisfy the conjugating condition, on the surface ∑2 while moving in coordinate S1. So the mathematical model derived from the equivalent transformation of conjugating condition in differential geometry is suitable for the conjugation of the computers discrete calculation and the analytical solutions of conjugating surfaces. This method, which can solve not only the solutions of analytical conjugating surfaces, but also the solutions of discrete conjugating surfaces, makes the solutions of conjugating surfaces intelligent and automatic.
