摘要
研究开发了参数化犁体CAD三维（3D）图形系统（PSCAD），以辅助犁体优化设计。将3D概念引入CAD，开发3D绘图与实体造型的三维图像模拟技术，保证了犁体研究与优化过程的直观和透明。该系统采用达到二阶参数连续的犁体曲面、样板曲线通用数学模型和参数造型，较传统建模方法光倾性有大幅度提高，可满足任意复杂及不同型式犁体的设计要求。
The parameterized 3D graphic CAD system is developed to aid optimizing and de-signing of various plow bottoms. Advanced 3D image simulation technology are introducedinto the system to guarantee visualization of developing processes. The C2-continuous mathmodels including 3D parameterizations in common use of plough surfaces are presented toproduce better smoothness than the traditional methods, and satisfy the designs of any typesof plow surface.
