PDM技术在机械可靠性设计分析中的应用研究

多领域工具集成是复杂产品虚拟样机设计仿真需要解决的技术问题之一.提出了一个面向服务集成、具有良好开放性、基于标准的、即插即用的机械可靠性设计分析多领域工具集成平台,以及基于产品数据管理(PDM)技术的机械可靠性设计分析虚拟样机体系结构.讨论了如何面向模型数据管理实现设计和协同分析过程中CAD/CAE工具与PDM的综合集成.最后,以某空间结构锁系可靠性设计分析为例,简要介绍了基于CAD/CAE工具的机械可靠性一体化设计、分析方案,以及如何采用应用封装技术实现基于PDM的机械产品可靠性协同建模和分析.

Study on Application of PDM Technology in Reliability Design and Analysis of Mechanisms

The multidisciplinary tools integration is one of the key technical problems in the Virtual Prototyping design and simulation of the complex product. In this paper,a service-oriented,better opening,standard-based and plug-and-play multidisciplinary tools integration platform for mechanism reliability design and analysis is presented,and the architectures of design and analysis of mechanism reliability based on PDM technology are given. What is discussed is the model data-oriented integration of management to realize the integration of CAD/CAE and PDM both in design and collaborative simulation periods. At last,an application example in space rendezvous mechanism is briefly introduced to indicate methods of integration design and analysis of mechanism reliability and how to realize PDM based collaborative modeling and analysis of mechanism reliability by using application packaging.
