Abstract: To identify the airworthiness requirements accurately in conceptual design,a conceptual graphs-based approach was proposed for identification of conceptual design requirements in civil aircraft,which included the analysis for classification of airworthiness requirements in view of function,behavior and structure.By extracting the design constraints of airworthiness requirements,its structured index was built based on conceptual graph ontology.Thus a matching degree-based approach for searching and indentifying the airworthiness requirements was proposed,and the corresponding index algorithm was developed.The effectiveness and feasibility of proposed methods were verified with practical exams.

摘要： 适航规章要求通常具有高度的概括性和一定的复杂性,为了在民机型号的概念设计阶段准确识别和把握相关适航要求,提出一种基于概念图的民机概念设计要求识别与获取方法。该方法从功能、行为和结构的角度分析适航要求的类型;抽取、提炼适航条款中蕴含的产品设计约束,采用基于概念图本体的方式建立其结构化索引,进而提出基于匹配度的适航要求识别和检索方法,并开发了相应的检索算法,同时进行了软件实现。通过实例检验了所提方法的可行性和有效性。
