Abstract: An algorithm of pattern groove centerline is proposed on the second development of tyre modeling.It is needed by studying how to insert pattern groove section and shape depth groove.It is current by abstracting mathematic modeling.Here basic algorithm and improved algorithm are listed.Improved algorithm produces more accurate data by fitting and interpolation on the curve based on basic algorithm.

Key words: Computer Aided Tri-Dimensional Interface Application(CATIA), tyre, pattern groove, fit, interpolation, modeling

摘要: 提出了在CATIA二次开发轮胎花纹沟造型时关于花纹沟中心线的算法,它是在花纹沟造型时针对如何插入花纹沟截面以及生成深度沟造型所必须具备的相关技术,抽象出数学模型具有相当的通用性。提供了基本算法和改进的高精度算法,改进算法在基本算法之上通过对曲线的拟合和插值来生成更为准确的中心线数据。
