Abstract

The functional requirements for mechatronical equipment are becoming more and more complex with the rapid development of modern production and technology, it has become the focus of research for the academia and industry. Aiming at the scheme design technology of complex diamond manufacturing special equipment, this paper conducted an in-depth study, including the functional scheme solving technology of complex diamond manufacturing special equipment based on functional semantic unit, the structural scheme variation technology method of complex diamond manufacturing special equipment based on extensible logic theory and the control scheme coupling technology of high-precision transmission system of complex diamond manufacturing special equipment based on mechatronical analysis. Moreover, these technologies have been successfully applied to the practical product design and develop process of complex diamond manufacturing special equipment.In the first chapter, the development situation of mechatronical technology was outlined, and also the definition and characteristics of complex mechatronical system was introduced. Then, the current study status at home and abroad and the research trend of complex mechatronical system were summarized. In addition, the introduction of scheme design technology of the complex diamond manufacturing special equipment was explained, and the primary research contents and the structure of this paper were given.In the second chapter, the functional scheme solving technology of complex diamond manufacturing special equipment based on functional semantic unit was presented. From the beginning of scheme design, the semantic feature was used as the tool to express the designer’s innovative idea. And the formal description of design semantic and its relative information was implemented. The functional semantic structural tree of complex diamond manufacturing special equipment was established. Then, it was decomposed to get the functional units of the equipment and the functional semantic unit was constructed, In addition, the functionl model of the complex diamond manufacturing special equipment was constructed and the function-structure mapping system was given. In the end, the detailed function solving procedures of diamond manufacturing special equipment was narrated.In the third chapter, the structural scheme variation technology of complex diamond manufacturing special equipment based on extensible logic theory was presented. After analyzing the inadequaties of the traditional product information model, the extensible theory was introduced into the information modeling of complex diamond manufacturing special equipment. The extensible composite model which is used to formally express the mechanical parts is established. Five kinds of variant operations which support the product innovative design are presented, and also variant design algorithm and procedures of conceptual strutures’ variant design are given.In the fourth chapter, the control scheme coupling technology of high-precision transmission system of complex diamond manufacturing special equipment based on mechatronical analysis was presented. The characteristics of mechanical-electronical coupling of complex diamond manufacturing special equipment were analyzed, and the three closed-loop high-precision servo control system with current loop, speed loop and positon loop was designed. The coupling control mathematiocal models of each subsystem were established, and then they were combined to generate the whole coupling control mathematiocal model of the high-precision transmission system of complex diamond manufacturing special equipment. At last, the performance of the high-precision transmission system of complex diamond manufacturing special equipment was simulated to verify the rightness and effectiveness of the above method.In the fifth chapter, the above technologies were applied to the practical development process of complex diamond manufacturing special equipment. The function of the equipment was decomposed with the functional semantics, and the functional sementical structural tree was achieved, and the mechanisms which can satisfy each subfunction were got from the function-structure mapping. Then, these mechanisms were reorganized to get the possible schemes, and the optimal one are selected. In the detailed design stage, with the five pair of variant operations mentioned in the previous chapter, the complex part in the equipment are variantly designed, until the structure of the part satisfied the design requirement. And in the end, the scheme, function and detailed structure of control system of the high-precision transmission system of complex diamond manufacturing special equipment are given. In the meanwhile, the design of hardware and software of the equipment were introduced.In the sixth chapter, the research results of this subject were summarized, and the future research direction are expected.
