Abstract：This paper presents collaborative virtual maintenance simulation and evaluation technologies to address the requirement of large mechatronics product maintainability design. By using virtual maintenance environment, with product digital prototype and maintenance tool model, maintainability design and evaluation work can be carried out at the early product design phase. Thus the integration design of product function and maintainability can be realized. Task oriented virtual maintenance prototype model and maintenance simulation operation process information representation method is presented. Firstly, as a multi-layer, multi-body structure, XML document scheme is used to realize product geometric topology and maintenance information reflection. This method enables product model data fast transferring over Internet and fast display in VE. XML based maintenance simulation operation process information model is also discussed. This method enables dynamic following and correct of complex process information, and provide basic information support for proposed collaborative system.
