In conceptual design of fusion blanket, we have got rid of traditional methods, in which a kind of information is isolated from others, but apply modern CAD technology to create the integrated information models, and apply modern CAE technology to analyze all the same models for different engineering. The info-composition of blanket info-model is analyzed, based on an idea, by which blanket model is unified in the whole procedure from research-oriented to engineering-oriented. A method of blanket info-modeling is established. After extracting and abstracting blanket features, the geometric model is defined by Backus Normal Form and associative concepts are normalized. Thereby, blanket variable geometric model of Fusion-Driven Subcritical System is created, and all kind of information is integrated with the geometric model, under the platform of Unigraphics NX.
The paper introduces a unified modeling and information integration for fusion reactor, based on the analysis of fusion engineering practice, in view of complexity of modeling fusion reactor. Characteristics of research-oriented modeling and engineering-oriented modeling are analyzed and compared. A principle of unified modeling in the whole procedure from research-oriented to engineering-oriented is advanced with its modeling-analyzing schema. As an example, blanket information model has been created by applying this principle and schema.
It is indispensable that the blanket information model should be created based on blanket geometric modeling for engineering design and analysis of fusion blanket. Structural features should be extracted from products and described in parameters before modeling with a parametric featured 3D CAD system. Constraints of the blanket structural features are analyzed and the main constraints are determined. These structural features are defined in parameters. Some methods are established, by which these structural features are created under a CAD system with feature modeling.
AbstrcatFusion blanket conceptual schemes emerge in endlessly. It is necessary that the existing blanket schemes should be surveyed and compared, further, that some rules in them should be extracted for us to advance a more reasonable and feasible innovative scheme. Also, it is indispensable that blanket should be classified and denominated, especially in programming for the intelligentized design of blanket. A method of blanket classification and blanket count and blanket nomenclature is put forward, by which blanket structural feature types are extracted and encoded according to possible used materials in blanket and their states in working. It is most important that a batch of innovative fusion blanket schemes can be discovered by this method.
