摘要
复杂产品制造业是国民经济和国家安全的重要基础,它的竞争将直接关系到国力的兴衰。虽然支持复杂产品设计的计算机辅助设计、计算机辅助工程、计算机辅助优化等等工具已经得到了广泛应用,而且也取得了了明显的效果,但是,设计、仿真和优化工具都是独立地支持复杂产品设计,缺乏协同设计、协同仿真和协同优化的深入应用,尤其是三者之间的协同集成。现有产品数据管理系统在文档管理、产品结构管理、变更管理、工作流程管理等方面提供了很好的支持,但是,对于复杂产品协同设计、协同仿真、协同优化及其集成的支持还不足。因此,本文针对复杂产品设计的特点,从协同集成角度出发,提出了复杂产品“协同设计、协同仿真、协同优化”一体化平台,对提升复杂产品自主研发能力、加快研发速度、提高设计质量具有重大意义。
The industry for complex products is important for national economy and national safety. Although tools like Computer Aided Design, Computer Aided Engineering and Computer Aided Optimization have been used successfully, and with prominent results, the design, engineering, optimization are mostly dealt with separately, and in this way, the data of complex product virtual prototype is difficult to be managed. Now PDM system can manage document, product structure, engineering change and workflow jointly, but it can not integrate CAX process（CAD modeling process, CAE simulation process, CAO optimization process）and CAX data （CAD digital model, CAE analysis result, CAO optimization project）. According to the features of complex product design, an integrated platform for collaborative design, simulation , optimization is proposed, which is useful in improving quality of complex products and reducing the cost.
