摘　　要：犁体曲面形状对土壤、作物品质和产量等均具有重要的影响,研究了基于水平元线法设计犁体时,导曲线等精确性的重要性和快速修改等问题,提出依据绘图思路建立曲线形成过程的几何关系数学模型,应用Matlab&Origin辅助编程获得拟合精确线条的拟合点或拟合关系模型,将获得的拟合数据导入CATIA软件生成犁体曲面模型。结果表明程序法辅助求解数学模型获得的犁体曲面模型精确且易于修改,从而达到对犁体曲面快速优化设计的目的。The important influence on soil, crop quality and yield, etc. was caused by the plough body surface. In this paper, a mathematical model of geometric relation of the plough body surface was proposed based on curve drawing process. Then more and more fitting points or the fitting relation model of the exact lines was obtained by MATLAB&Origin, and the fitting data were imported into CATIA software to generate the plough surface model. The results showed that the surface model of the plow body obtained by the program method is accurate and easy to modify, so as to achieve the purpose of rapid optimization design of the surface of the plow body.
