Research On System, Technology And Its Application Of Rapid Research And Development

Rapid Research and Development (RRD) is a new conception brought out according to the equipment developing situation in the new period. Till now, there have been few researches in RRD, and thus RRD is an exploratory new field. The main research works and achievements are listed below:Firstly, on the basis of the current situation of equipment developing, the cycle model of equipment development is constructed using systematic methodology. The technology for implementing RRD is referred. The connotation of RRD and RRD System (RRDS) is then defined. The Concurrent Researching Model is built, and the technology structure is identified. Aiming at constructing RRDS, the architecture of RRDS is built, and the key technologies are identified.Secondly, according to the stratagem of equipment rapid development by serialization, this dissertation puts forward the rapid design model based on modular design technology. To the functional module design, this dissertation constructs the design model for functional module, studies the method to map user requirements to technological requirements based on QFD, builts the hiberarchy model of functions and investigates the method to identify functional modules. To the structural module serialization, the method for creating base structural module of equipments is researched and the module architecture is built. To the module combination, the configuration model is built, the technology to map technological requirements to the feature parameters of modules is researched and the retrieval method based on shape features is proposed, all the above form the technological base for the equipment combination design.Thirdly, this dissertation builds the model of GT-based Rapid Trial-Manufacture, proposes methods for process optimization according to the primary features of parts.Consolidating trial-produced parts of little batch into groups according to the primary features,that avoids designing the repeated processes and diversifying the process files of parts belonging to the sametype. The architecture of the production planning system that syncretizes the ideas of MRPII, JIT and Network Planning is also constructed, and several key technologies are researched, which includes: to construct the information model, to generate network plan using the decomposition method of MRP, to optimize the network plan, to control the changes and to monitor the execution of the plan. The management of dynamic BOM and its configuration model for serialization are described. And the algorithm of transforming from design BOM into manufacturing BOM, building ofmonolayer BOM and the traversal for BOM is researched.Fourthly, the global information model for equipment developing is constructed according to the developing information analysis; the architecture of the platform is put forward according to the requirements of information interacting, document management, etc. And the technology of document management, message collaboration, workflow management and security management is researched here. The platform implements the unified storage and management in developing procedure, which can browse and exchange the information according to the workflow of developing. Information can be exchanged efficiently. Also this platform has high security performance, and is easy to be extended or pruned to meet different kinds of application requirements.Finally, the RRD system for a equipment is built using the achievements in this dissertation. The Modular Design System, Production Planning System, Information Integration Platform which supports research procedures are developed for the RRD system. The application effect is analyzed in the end by Comparing with that of the past.
