三维CAD系统中装配尺寸链提取及其实现技术的研究
|
摘要
本文结合国家自然科学基金项目“基于产品几何技术规范的集成公差设计理论与方法”(50275136)和浙江省自然科学基金项目“面向CAPP的工序公差设计研究”(502016)，开展了三维CAD系统中装配尺寸链自动提取及软件实现技术的研究，在三维CAD系统SolidWorks下开发了相应的原型系统。论文的主要研究内容如下：
第一章：回顾了计算机辅助公差技术的发展历史和研究现状，分析了其中的关键技术，提出了本文的研究内容和总体框架。
第二章：分析了ISO／TC 213公差语义，介绍了产品几何技术规范(GPS)对特征的定义及其检测过程，阐述了其中的二元原则，研究了特征的各种属性。
第三章：阐述了TTRS理论中几何特征的分类，分析了参数化三维CAD系统(SolidWorks)的约束机制。根据变动几何约束理论，给出了配合回路的生成规则，提出了面向尺寸链的变动几何约束网络的生成方法。
第四章：采用数据库来表达装配尺寸链信息，给出该数据库结构的定义，构建了一种面向装配尺寸链的数据库。
第五章：提出了基于三维装配图的尺寸链自动生成策略。在装配图上指定封闭环后，系统根据配合树在装配图中提取装配约束关系以及相关尺寸信息，生成面向尺寸链的变动几何约束网络，然后搜索其最短路径并构建面向尺寸链的装配数据库，根据数据库自动生成装配尺寸链。
第六章：在分析开发平台(SolidWorks)、开发工具(SolidWorks API)和开发语言(VB)特点的基础上，根据前面章节所述的理论和方法，开发了嵌入在SolidWorks中的装配尺寸链提取原型系统，并给出实例验证。
第七章：对本文的研究内容进行总结，对需要进一步解决的问题和以后应开展的工作进行了探讨和展望。
