[Abstract]:In the process of implementation of MBD technology, 3-D process is the key point and key point, and it is also the concrete performance of enterprise in production and manufacture level. As the carrier of 3-D process, the modeling process and process evaluation of MBD process information model is studied, and its modeling process and process evaluation are studied. It helps to analyze the process of the product in the early stage of the design, reduces the repetitive labor of the process designer, and saves the time of research and development and the cost of production. MBD process information model can be used as the sole carrier and basis of product information, which ensures the accuracy of information transmission, speeds up the production efficiency, and improves the product quality in an all-round way. It can meet the requirements of information accumulation and knowledge base expansion, and improve the competitiveness, adaptability and survivability of enterprises in modern manufacturing industry. Taking the MBD process information model as the research object, the definition, information expression, modeling method and process evaluation of the model are studied and discussed, and the MBD process information model of copper sleeve is established under the environment of SolidWorks. The secondary development tool Visual Basic6.0 is used to extract and evaluate the process information of the model, which validates and supports the viewpoint of this paper. Firstly, the development and application of MBD technology at home and abroad as well as the research status of MBD process information model are discussed, and the shortcomings of MBD process information model research are pointed out. Secondly, the definition of MBD process information model is analyzed and supplemented, and the basic structure of MBD process information model is discussed in detail. Based on this, the three-dimensional hierarchical expression of process information is discussed. A method of labeling MBD process information is presented. Thirdly, according to the meaning of process evaluation of MBD process information model and the aim of MBD process information model, the process evaluation scheme of MBD process information model is put forward, and the technical basis of the evaluation scheme is introduced. Finally, taking a copper sleeve part as an example, the MBD process information model of the copper sleeve is established, and a small MBD process information model evaluation system is developed. The MBD process information model of the copper sleeve is evaluated. This paper demonstrates the point of view.
