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 reliabili- ty by using application packaging.
