基于CATIA的标准件库设计与实现

CATIA-Based Design and Implementation of Standard Parts Library

对基于CATIA软件的航空产品标准件库的关键技术和实现方案进行研究,提出一种基于CATIA的标准件库实现方法.对基于CAAAPI的标准件实体建模、零件参数表设计、基于Catalog的标准件层次结构设计及标准件的数据库存储模式设计等创建标准件库的关键技术进行描述,开发了标准件库系统.标准件库覆盖国标、航标、企标、军标的紧固件、机体构件、系统构件、管路系统构件、电气操纵构件等零件类型.

Design and implementation of a standard part library for aircraft product are studied in the paper. Key techniques such as geometric modeling of standard part, design of the part＇s design table,catalog-based standard part hierarchy, and database storage scheme are discussed in detail. In order to integrate with CATIA, CAA API for CATIA V5 is used. The standard part library developed covers common parts in the national standard, the aeronautic standard, the enterprise standard and the army standard. Detailed groups in the library include fastener, airframe components, system components, routing and electrical components, etc.
