摘　　要：分析了并行产品开发的特点，提出了并行产品开发的信息集成框架，并从８６３／ＣＩＭＳ关键技术攻关项目“并行工程”的需求出发，参照ＳＴＥＰ应用协议ＡＰ２１４，建立了并行工程产品特征信息主模型，同时利用ＳＴＥＰ开发工具，通过对ＣＡＤ特征再建模的方法支持ＣＡＤ与ＤＦＭ／ＣＡＰＰ／ＣＡＭ／ＣＡＦＤ的信息集成；利用Ｄｅｌｔａ文件管理工具实现产品数据设计版本管理。The characteristics of concurrent product development is analyzed and an integrated framework for product data integration of concurrent engineering is presented. A feature based information model referred to STEP AP214 for the concurrent engineering application subsystems is proposed. As the ST Developer tools used, the information integration between CAD and DFM/CAPP/CAM/CAFD is realized to get manufacturing features from CAD through standard data access interface. The Delta file management tool of STEP_Developer is used to enable product data management for design regeneration.
