中文摘要：
为提高产品设计效率,研究了组件框架技术,借助CATIA二次开发平台,在参数化建模技术的基础上实现对飞机典型零件的变型设计,快速提取特征信息,实现智能化操作.利用面向对象的程序语言,开发出与CATIA系统集成的变型设计模块,能够提高飞机典型零件的设计效率.以飞机典型零件机加件中的拉杆为例,对变型设计方法的验证表明,利用CATIA二次开发技术以及CAA编程工具,能够对飞机典型零件参数化建模,实现变型设计.
英文摘要：
To improve the efficiency of product design,the technology of component framework has been researched. Using CAA of CATIA secondary development,the typical parts of the product variant design was established on the basis of the parametric modeling technique,the feature information was extracted quickly and the intelligent operation was realized. Using object- oriented programming language,a variant design with CATIA system integration module has been developed,the product efficiency of plane typical parts was improved greatly. As an example,the pull rod in the typical parts machine and the methods of variant design are verified.
