面向装配的智能变型设计技术及应用研究

Intelligent Variant Design Technology Based on Assembly Model and Its Application

产品变型设计的基本思想是通过改变已有的系列产品或设计实例来适应新的设计需要.针对变型设计的基本特点,以装配环境下基于实例的推理为基础,结合工程CAD中的模板技术,提出了面向装配的智能变型设计理论和方法.通过对SL1126柴油机产品结构特征深入研究,获得该产品结构设计知识,对产品的设计任务进行抽象和分类,应用Pro/ENGINEER及其二次开发工具Pro/ToolKit,开发了一个柴油机整机产品三维参数化CAD系统的原型,实现了产品整机的参数化设计,验证了该方法的可行性.

The main idea of variant design is to adapt the existing product or design case to the new requirements. In terms of the feature of structural module and the process of structural modular design ,through abstraction and classification of design task of SLll26 diesel engine,we suggest a plan that has general guiding significance to three dimensional parametric design for whole product based on CBD and integrated with the CAD method. An Intelligent variant design system is studied for assembly model based on Pro/E and Pro/ToolKit.
