Research On Simulation Integrating Platform For Multidisciplinary Virtual Prototyping

This paper introduces the progress of the research program of integrating platform for multidisciplinary virtual prototyping, including the architecture and key technologies of the integrating platform. Special attention is paid to an open, standard based virtual prototyping supporting platform for primarily supporting multidisciplinary virtual prototyping engineering of complex product, which is developed and integrated recently by the author and their colleagues. Also addressed are development techniques for the tools required by the platform, where all the required functional modules are integrated. In the end, two application development cases are illustrated, which are typical examples based on supporting platform. This paper includes 5 chapters. Chapter 1 summarizes the development of integrating platform for multidisciplinary virtual prototyping. Chapter 2 introduces the architecture of HLA, which is the core technology of current virtual prototyping. Chapter 3 introduces the characteristics and the system structure of the integrating platform for multidisciplinary virtual prototyping, which based on pre-research program of the General Armament of PLA in the Tenth Five-Year Plan. Chapter 4 describes in detail the integrating and implementing techniques of multi-field tools based on HLA in integrated platform of multidisciplinary virtual prototyping. Chapter 5 concludes this paper with a possible study direction in the future. Recently, according to the effect of new products R&D and manufacture with the insistent requirement to meet the dynamic market demand, the Virtual Prototyping technology, which is based on system modeling and virtual science, has been rapidly developed. Especially as the representatives, a variety of CAx/DFx technologies have had many achievements in different levels of R&D studies and been successfully implemented. At the same time, a kind of complex technology which can support coordination between different units and scopes becomes the development hot spot in manufacture industries. The successful application of virtual Prototyping in Boeing 777 is a typical example. The complex products series refer to the complexity on customer demand, product composition, R&D technology, manufacture and project management. Typical product are spacecraft, airplane, automobile, complex mechanical and electrical product, armament system and so on. The complex product development involves many different subsystems, technologies (usually involves machinery, electron, software and system control and many other multi-disciplinary areas), many personnel, tools and the development systems even interactive characteristic; moreover, it also has complex alternately relationships with the external environment. Therefore, the complex product is a challenge task for the traditional technology, development tools and project management method. This paper introduces the progress of the research program of integrating platform for multidisciplinary virtual prototyping, including the architecture and key technologies of the integrating platform. Special attention is paid to an open, standard based virtual prototyping supporting platform for primarily supporting multidisciplinary virtual prototyping engineering of complex product, which is developed and integrated recently by the author and their colleagues.

Chapter 1 summarizes the development of integrating platform for multidisciplinary virtual prototyping. Chapter 2 introduces the architecture of HLA, which is the core technology of current virtual prototyping. Chapter 3 introduces the characteristics and the system structure of the integrating platform for multidisciplinary virtual prototyping, whichbased on pre-research program of the General Armament of PLA in the Tenth Five-Year Plan. Chapter 4 describes in detail the integrating and implementing techniques of multi-field tools based on HLA in integrated platform of multidisciplinary virtual prototyping; and based on the independent development of Virtual Prototyping Supporting Platform, especially for the analysis of virtual systems levels, to reduce the number of prototype machines produced and the experimentation, use the virtual technology as a basic through the coordination virtual platform to connect different models, analysis software and build up a virtual environment which can support the complex coordination system analysis; also to support the design digital products and test whether the controllability and mechanical capability meets the product requirements. According to the structure system requirements to structure system by the control system and the overall astronautics complex products as a whole, in the product design process, the ADAMS, CATIA, MATLAB and many other software are used to analyze and simulate the product virtual Prototyping combined systems and reprocess the final results; as a result, many goals are achieved such as control system kinematics and kinetics emulation and optimization of system control and structure design. Under the visible environment, the virtual Prototyping of the complex aircraft products are completed expressed. Chapter 4 in detail introduces the multi-subjects virtual Prototyping simulation combined platform based on HLA tools; a deep study of second time development method which is supported by multi-subjects tools such as MATLAB,ADAMS,CATIA; select requirement function for the platform; take a use of the element self-create function; close functional units into elements and send it to model database; prepare for self-create units and combined units; join in the combined simulation for the whole system. Chapter 5 concludes this paper with a possible study direction in the future. Enhance the usage and study of internet technology, payattention to the knowledge engineering in the virtual prototypical environment, study the application of internet technology on credibility, standard, safeness, intelligentize and compatible controllability basic information supporting platform and system; furthermore, to reinforce, develop and consummate the current platform to develop a new simulation platform with independent intellectual property rights and be able to support a longer complex product life cycle, the coordination virtual prototype project, and even SBA (Simulation Based Acquisition).
