%X 为了降低高速滚动轴承打滑失效试验台设计中知识获取的复杂度,结合知识流理论对试验台集成设计过程进行了知识梳理与基于流程分解的知识解耦,在对功能质量约束需求进行分析的基础上研制了打滑失效试验台。提出了一种支持产品全生命周期设计的一体化知识集成框架,并基于这一框架对打滑失效试验台从需求分析直至交付的全生命周期设计过程中的设计知识及其与设计过程的集成模式进行了研究。建立了高速滚动轴承打滑失效试验台集成设计的知识流模型,对试验台集成设计服务及其知识流动情况进行了分析;研究了分布式资源环境下设计知识服务的发布与发现机制,对建立的资源单元进行了基于网络的知识服务注册与发布,以利于分布式资源环境下用户的搜索与发现。研究结果表明,从知识流视角出发对试验台集成设计进行研究是可行的,有助于提高设计效率与质量。<br>Skidding damage of rolling bearings often affects the service performance of machinery, which is a complex problem related to tribology, dynamics, materials science, thermodynamics and other multi？？disciplinary knowledge. In order to reduce the complexity and to improve the efficiency of knowledge acquisition, the design knowledge is clarified and decoupled based on the knowledge flow theory, and then the skid damage test rig for high？？speed rolling bearing is developed based on the function？？quality？？constraint requirement model. A model of the knowledge integration framework is proposed, which provides an overall technical support for the whole life cycle design process under distributed knowledge resource environment. The test rig design services and knowledge flow are analyzed based on the knowledge flow model. The process and implementation method of knowledge service under distributed knowledge resource environment are analyzed. The knowledge units are registered and released on the knowledge service platform for modern design, which can help search and discover users under the distributed resources environment. The result shows that the integrated design of skid damage test rig based on knowledge flow is feasible and helpful to improve design efficiency and quality
