Study on the Model-driven Method for the Satellite Overall Design
-
摘要: 为了提高卫星总体设计的自动化程度,本文以航天卫星型号研制为研究对象,提出了一种模型驱动的卫星总体设计方法。首先分析了模型驱动的卫星总体设计流程;接着,构建了卫星总体设计本体知识库,实现相关模型的形式化描述;然后,分别论述了需求分析、功能分析及结构分析的建模过程。该方法以用户需求为输入,在相关本体知识库及实例库的支撑下,能够智能化地实现需求分析、功能分析及结构分析,为基于模型的系统工程提供一种智能化的建模工具。最后,以某型号卫星为例,验证了本方法的有效性。Abstract: In order to improve the automation degree of the satellite overall design, taking the aerospace satellite asexample, a method of model-driven for satellite overall design is proposed. Firstly, the model-driven process forsatellite overall design is analyzed. Secondly, the ontology knowledgebase for satellite overall design is constructed,which realizes formalizing description of the models. Thirdly, the models of requirement analysis, functional analysis and product structural analysis are constructed respectively. Taking the user requirement as input, the requirement analysis, functional analysis and product structural analysis can be dealt intelligently supported by the ontology knowledgebase, which provides a kind of intelligent modeling tool for model-based system engineering. At last,taking some a satellite as example, the effectiveness of this method is verified.
