[Abstract]:In this paper, with the aid of the National 863 Program (2009AA04Z148), a CAD and analysis tool for the structure of micro-electromechanical system with independent intellectual property is developed, and the data conversion of multi-body dynamics model is studied. It provides a feasible scheme for the design of the model data interface between the computer aided design and analysis software and the virtual prototype analysis software ADAMS, and extends the modeling function of the computer aided design and analysis software for the structure of the micro electromechanical system. Reduce repeated modeling and improve the versatility and compatibility of integrated design tools. Based on the theory of multi-rigid body dynamics modeling, this paper studies the model analysis and representation of multi-body dynamics, including the relationship between model and model elements, the classification of model elements, and the description of model topology. This paper analyzes the file characteristics and syntax specification of the model description file (cmd as the suffix name), and summarizes the representation and distribution of the model element information in the model description file. Taking the model elements such as component, force, constraint and drive as the research object, the information extraction method of the model elements in the model description file is studied, and the relationship between the model elements and the model elements is established. The data structure of the model data converter with complete topological connection is formed. Using C BUILDER 2009 as the development tool, the development of model data converter is realized. The application example of model data converter in integrated design tool is given, which verifies the feasibility and validity of this paper.
