Abstract: To realize the information sharing of different disciplines in complex product development process, and to eliminate the obstacles of system integration, collaborative simulation and system optimization, a digital prototype construction method based on ontology meta-model was put forward. The feasibility of integrated modeling based on ontology meta-model were analyzed and a core package for meta-model by using extended model of UML was constructed. Based on the ontology theory, the concepts and their relationships in complex product collaborative development domain were analyzed, and information integration framework of multi-disciplinary collaborative domain was established. The digital prototype model which covered product information, development method information and development process information was built based on ontology meta-model. The abstract evaluation, granularity decomposition and multi-disciplinary coordination of complex product in development process were supported by proposed models. The active phased array radar was used to illustrate the models.

Key words: ontology meta-model, integrated modeling, digital prototype, multi-disciplinary collaboration, product development

摘要： 为实现复杂产品研发过程中不同学科的信息共享，消除系统集成、协同仿真和系统优化的障碍，提出了基于本体元模型的数字化样机构建方法。分析了基于本体元模型的多领域集成建模的可行性，利用统一建模语言的扩展模型构建了本体的元模型核心包；基于本体理论分析了复杂产品协同开发领域的概念及其关系，构建了多学科协同领域信息集成框架；基于本体元模型建立了涵盖产品定义信息、研发方法信息和研发流程信息的数字化样机模型，支持产品在研发过程中的多抽象层次演化、多粒度层次分解和多学科协调优化，控制复杂产品的整个研发过程。以有源相控雷达为例对所提方法进行了说明。
