摘要: 为便于构建计算机自动分析系统,提出共轭曲面自适应分析的离散解析原理,即曲面的分析按离散点进行,在每一离散点上遵循共轭曲面解析原理。共轭曲面曲率分析是共轭曲面理论的一个重要内容。认为创成曲面Σ1决定于母曲面Σ2和相对运动的共同作用,通过对Σ2和相对运动的综合分析,获得Σ1上相应点的曲率特性。从共轭条件的导数形式出发,推导出由母曲面Σ2及相对运动获得创成曲面Σ1曲率特性的公式,在数学模型上将离散运算和解析原理结合起来,与作者此前提出的共轭曲面自适应综合的离散解析原理相统一。“离散解析原理”使得计算机智能化、自适应处理共轭曲面问题成为可能,为相关CAD/CAM应用系统开发及共轭曲面理论的广泛深入应用奠定坚实的基础。

Abstract: The discrete and analysis principle of conjugating surfaces for adaptive analysis is proposed to help to construct computer system in that the analysis of curvature of conjugating surfaces is a very important aspect in the theory of conjugating surfaces. The generated surfaceΣ1 is regarded, taking the generating process of conjugating surfaces into account, as the resultant of the interaction between the generating surfaceΣ2 and the relative motion betweenΣ1 and Σ2. So the characteristics of Σ1 can be decided through analyzing the characteristics of Σ2 and the relative motion. And the authors derives the formula of Σ1’s characteristics in the form of Σ2 and the parameter of the relative motion, the mathematical forms of which the suitable for the combination of the computer’s discrete calculation and the analytical solutions of conjugating surfaces intelligent and automatic and is helpful to construct highly flexible CAD/CAM application system.
