The overall product is designed to be mass-produced product as a sample, and its theory and technology cannot be applied for innovations of large-scale capital goods, which have a high value, high-tech, high cost and high customer customization features. Problems and challenges for development of Complex Equipment Systems (CoES) are significantly different from large-scale manufacturing products, and a new theory and technology system must be established. It is also the research objective of this thesis. The theoretical contributions of this thesis are that the concept of complex equipment system has been defined, and a experiential process model in the CoES development (CoESEPM), and three technology systems for the CoES development, including Reverse Engineering in the Development of Complex Equipment Systems (CoESRE), digital Assembly molding in the Development of Complex Equipment Systems (CoESAM) and Product Emboding in the Development of Complex Equipment Systems (CoESPE),have been established in this thesis. Research achievements of this thesis will have a theoretical significance and practical significance of engineering. This thesis is divided into seven chapters, the main content and opinions are as follows.The principal contribution of Chapterâ… is which has defined the concept of Complex Equipment System with the related characteristic in product, innovation, technology, production and market, this thesis has been firstly defining the concept of CoES. CoES is clearly a superior product that it is large, complex and expensive and it is manufactured in single-piece and there is no clear distinction between development and production for CoES. For typical CoES characteristic, a CoES development process should focus on experiential, so as to improve the success rate of the development results.The foremost contribution of Chapterâ…¡is which has created an experiential process model in the CoES development, focusing on the archetypal characteristic of CoES. The CoESEPM model is experiential, iteration and digital; CoESEPM model classified CoES development process as three stages, including reverse engineering phase, redesign development phase and the redesign implementation phase. Then, focusing on the task for each phase, this thesis in the chapterâ…¢,â…£andâ…¤has established CoESRE technology, CoESAM technology and CoESPE technology. The highest contribution of Chapterâ…¢is which has established Reverse engineering technology systems in the CoES development. CoESRE, including the disassembly, CAD model reconstruction in reverse engineering and rapid prototyping manufacturing in Reverse Engineering, mainly solves the problem for reverse engineering of the design and structure in CoES development of existing products (benchmarking products).The core contribution of Chapterâ…£is which has established an assembly molding technology system in the CoES development. CoESAM, mainly including the information input and information output in the assembly molding process, can give an analysis and evaluation for the CoES Assembly before manufacturedThe principal contribution of Chapterâ…¤are which has established a product embodying technology systems in the CoES development. CoESPE, including product embodied in the assembly simulation, product embodied in the kinematics simulation, product embodied in the dynamics simulation, product embodied in the work simulation, product embodied in the control simulation, product embodied in the manufacturing simulation, can complete simulation for the variety of CoES performance, so as to to optimize performance and improve the design quality for CoES.The core contribution of Chapterâ…¥are which has practiced the CoES development process. With the CoESEPM model and the CoESRE, CoESAM and CoESPE technology, this thesis has given a development process of a stamping measuring machine and an implementation process in UGNX, ADAMS and ANSYS software. The practice has proved that the CoESEPM model and three technologies in this thesis is feasible in theory and practical in the engineering.Chapterâ…¦is a summary and outlook. A summary of the full text of this thesis, key innovations and future prospects of research difficulty has been provided.
