<正>运用基于形状特征线的参数化造型方法建立了马蹄腿的数学模型。根据对马蹄腿尺寸的分析，给出了马蹄腿腿型的典型尺寸关系。按照ＮＵＲＢＳ曲线曲面的构建方法作实体造型，成为初始设计、产品建模及修改、多方案比较和动态设计的有效手段，并为数控机编程等后处理模块打下基础。

The mathematical model was established according to the structural character of horse-hoof-shaped leg by using parameter modelling method which was based on character line of shape. With the analysis on the size of the horse-hoof-shaped leg,the relationship of the typical size was shown. The practical models were de- signed according to the method of shaping NURBS curve and surface. They were very effective for primary de- sign,model establishment,modifying and comparing of projects,as well as for dynamic design. It also can be a basis for consequent dealing module,such as programming for NC machine,etc.
