基于CATIA平台的汽车标准件参数化三维图库开发

Development of Parametric 3D Drawing Library for Automobile Standard Parts Based on CATIA Platform

汽车使用的标准件较多,并且同类标准件结构相似。为减少标准件设计的工作量,使用VB设计交互界面,ACCESS数据库存储参数,采用CATIA变量驱动建模的方法,详细说明了汽车标准件参数化三维建模和三维图库程序的开发方法,并阐述了三维图库的功能结构和应用实例。该应用方便实现了快速生成标准件三维模型的功能,提高了产品设计效率。

Standard parts are used more frequently in automobile,and some standard parts are similar in structure. In order to reduce labor intensity,making use of VB to design user＇ s interface,using ACCESS database to storage parameters,using CATIA method of variables driven modeling,a development method of 3D modeling and 3D gallery program standard parameters in automobile is given description in detail.The function structure and application of 3D graphics library are explained. The application realizes the rapid generation of standard parts 3D model and improves the efficiency of product design.
