基于CATIA的组件库建库工具的设计与实现

Design and Implementation of CATIA-Based Construction Tool for Component Library

为在CATIA上创建典型工装组件库,并实现对组件的查询、预览、调用及对主要参数的三维显示等功能,文中在研究标准件库的创建、调用过程的基础上,提出了组件库建库工具的总体框架,分析了组件的实体建模方式、参数表设计和基于CAA API的组件库预览与调用等建库关键技术和实现方案,以CATIA为平台设计并开发了组件库建库工具.企业实际应用表明,该建库工具适用性强,能够提高设计效率和产品互换性.

In order to construct a typical CATIA tool component library, to implement the query, preview and use of the components, and to display the main parameters in a 3 D space, the construction and query processes of the standard part library are investigated, and a general frame of the construction tool for the component library is put forward. Some key techniques for the library construction and the corresponding implementation methods are then discussed, such as the modeling method of the component entity, the design,of the parameter table and the CAA API-based preview and instance of the components. Moreover, a construction tool of component library is designed and developed based on CATIA. The tool is finally applied to an enterprise. The results show that the tool is of great applicability and helps to improve the design efficiency and production interchangeability.
