Unified Product Modelling And Simulation Technology For Complex Mechatronic System

With the serious competition in the international market and the attention to knowledge privilege protection, the original product design is the key problem for the companies. Cross-domain system modelling approach,multiple-disciplinary simulation and collaborative development process management technology for complex mechatronic system are the key technologies during the development process of complex mechtronic system, which provide strong support. The research was based on the following research projects:(1) Key Research Project of Science and Technology Development Program of Shandong Province:Research on virtual prototype technology of complex product. (2) Key Research Project of the Supporting Program of Science and Technology of State 11th Five Years Plan:Research on key equipments of coal mine full mechanized mining face in complex mining conditions. (3) Shandong Natural Science Foundation for Distinguished Young scholars of China:Resource sharing and virtual prototype technology for cooperative development of complex product.Unified Product Modelling approach and cooperative simulation technology for complex mechatronic system have been studied in detail in the dissertation and corresponding research and application achievements have been made.(1) Multiple-disciplinary cooperative system modelling approach for complex mechantronic system was studied and Unified Product Model (UPM) based on C&CM for complex mechatronic system and Unified Product Modelling methodology based on UPM was given originally. The basic elements, the description method and process were given. UPM shows the internal structure of system model and the coupling relationship among domain models. According to UPM, it can ensure that all the team-members can always get the coherent view of the 'single source of truth' of mechatronic product, which could not be done in previous time. UPM can ensure the consistence from the genesis and eliminate unnecessary iterations so that it can help to shorten time to market and reduce cost by means of a more efficient development process.(2) Ontology was used in the development process of complex mechatronic system and the description process of UPM based on ontology was given. According to this description, both the man and computer can understand it easily, which can assure the knowledge sharing and inquiry of information. It can provide the basis for knowledge communication at the system design stage and knowledge sharing and reuse at the late stage. (3) With collaborative simulation technology for Complex mechatronic system in the core, a cooperative simulation framework based on HLA (High Level Architecture) was.provided, which gives a reference structure for the multiple-disciplinary cooperative simulation in produce development domain Collaborative simulation modelling approach based on UPM and HLA was given, this approach can help to set up the internal connecting relationship between design model and simulation model that has not been given in existing research. On this basis, modelling of cooperative simulation and cooperative simulation running management technology were studied, Simulation running management system was designed and developed.(4) Collaborative development process management technology for complex mechatronic system was stuied from.the point view of process management, model management and data sharing.The management of staff, data and information involved in the process of unified product modelling, domain modelling and cooperative simulation etc was realized, which can support the concurrent cooperative development of complex mechtronic system.(5) A multidisciplinary cooperative development platform was studied and the whole framework and elements of this platform were given. The platform was realized by programming. Application of the multidisciplinary cooperative development platform was given using one Robot Arm design.process as an example.
