摘要
本文根据车身设计实践中对曲线曲面的要求建立了光顺处理的判别准则。以最小能量法为数学模型的基础,建立了车身曲线曲面计算机辅助光顺处理系统。该系统可以对一组曲线(面)连续地进行光顺处理、光顺性评价及其作图,具有较强的人机交互功能,运行可靠。本文所采用的方法及所建立的系统同时适用于其它行业(如飞机、船舶等)曲线曲面的造型设计。
In accordance with the functional requirements of curves and Surfacesin automobile body design, authors propose some criteria for evaluatingtheir smoothness. Based on the mathematical models of minimum energy,a smoothing system for automobile body design has been developed. Thesystem can smooth, evaluate and draw a group of curves and surfaces co-ntinously, possesses good man-machine interface and operates reliably.This method and system may be applied to the airplane and ship designas well.
