Integrated Simulation Platform Based On Functional Mockup Interface And Its Application On Aerospace Engineering

Higher dependence on simulation system is required in the Research andDevelopment Process of the aerospace products, due to their characteristics such as longR&D cycle, expensive costs. Because of the broad range of different disciplines areinvolved in the field of Aerospace Engineering, in order to solve the problem ofAerospace Engineering simulation, research on Co-simulation and development of themulti-disciplinarity simulation platform have become the very important goal. Based onthe discussed demands, this thesis has illustrated the design and development ofintegrated simulation platform based on the interface standards of Functional MockupInterface Model. The research work is mainly presented as following aspects:First of all, the interface standards are introduced on the FMI model, whoseproperties are also depicted in detail. The universalization of the platform interface isdesigned according to the FMI standard. Meanwhile, the application patterns of thestandardized simulation model of FMU are described.Secondly, the scheme of integrated simulation platform are lay out according to thefunctional analysis of the integrated design platform, and uniting the characteristics ofexisting commercial simulation platform. Integrated simulation platform uses the.NETFramework architecture, with C#language as the software development language. Thepage development, employing the WPF framework, is proceeding in the interactivelayer. Thus the page layout design, which is based on the XAML configuration language,is separated from the functional exploitation of page development. In the applicationlayer, the pattern of model function code encapsulated into a dynamic link library isadopted, as to process the function of the simulation module. This improves thescalability of integrated design platform. And the data layer uses the ADO data mappingtechnology, simplifying the operations of data access, therefore the developmentefficiency and operation efficiency of data access layer are enhanced.Finally, this thesis uses the hydrodynamic problem of the navigation bodystationary flow as an example, introduces particularly of the functions such as theself-research module encapsulation method, platform model management, processdesign. After the above operations, the FMU model, which is configured with severalparameters, is running on integrated simulation platform. And the results verified thefeasibility and interactivity of the co-simulation technology based on FMI interfacestandards are of good quality.
