摘要
皮鞋鞋楦变跷设计是鞋楦CAD/CAM技术中的重要内容。介绍了在鞋楦离散造型建模下用已知平面切割鞋楦体求交线交点的自适应求交(AT)算法的基本原理,即将已知平面上的交点逼近问题转化为对鞋楦某一截面上所求点的逼近,在此基础上介绍了用该方法在变跷设计中的应用。实现了变跷前后鞋楦数据的相互转换,确保了整个皮鞋鞋楦CAD系统数据格式的统一。给出了算法具体实现思想和应用实例。
Deformation design is main content of shoe last CAD system. This paper introduces adaptive tangency (AT) algorithm, which is used to calculate the sectional curve when a known plane section shoe last under a discrete model, and describes its application in shoe last deformation design. Shoe last data can be converted each other in shoe last deformation design, which ensures data format standardized in whole CAD procedure. The detailed algorithm in deformation design is fulfilled and an actual example is given, which shows AT algorithm's application is successful.
