摘要
基于CATIA参数化建模及CAA开发,介绍一种跨节距花纹设计的方法。该方法主要包括跨节距花纹模板制作和整周拼合。跨节距花纹模板制作包含跨节距相关参数创建、跨节距2D线框设计、跨节距3D曲面设计和跨节距3D实体设计4个阶段,利用CATIA知识工程及三维建模技术,实现以节距参数和旋转角度为主要发布参数的模板封装。之后利用CAA编程技术,调用跨节距花纹模板,快速实现了整周花纹的拼合,缩短了轮胎开发设计的周期、降低了开发成本、提高了设计自动化的水平。
Based on CATIA parametric modeling and CAA development,a method of cross pitch pattern design was introduced. The method mainly included the creation of cross pitch pattern template and whole cycle assembly. The creation of cross pitch pattern template included four stages:cross pitch related parameter creation,2D wireframe design,3D surface design and 3D solid design. Using CATIA knowledge engineering and 3D modeling technology,the template packaging with pitch parameters and rotation angle as the main release parameters was obtained. Then,using the CAA programming technology and calling the cross pitch pattern template,the whole cycle pattern could be assembled quickly,which shortened the cycle of tire development and design,reduced the development cost and improved the level of design automation.
