Abstract: For the problem that current methods for performance prototype of quantitative description and modeling theory was not yet mature,the functional devision and design procedure for performance prototype were analyzed based on systems engineering method and performance prototype verification process.The performance prototype collaborative design and simulation business was analyzed,and a collaborative performance prototype conceptual modeling method based on ontology meta model was proposed by combining with ontology modeling method.The collaborative conceptual modeling of a hypersonic vehicle was used to show the performance prototype collaborative modeling case,and a performance prototype ontology model library was constructed with Protégé tools which could better solve the lack of multidisciplinary product model output and the problem of redundant information.It could explicitly express domain knowledge and promote the concept of semantic consistent between different areas.

Key words: performance prototype, collaborative modeling, ontology meta model, aerospace products

摘要： 针对目前性能样机的定量描述和建模理论与技术尚不成熟等问题,根据系统工程综合集成方法和性能样机的性能验证过程,对性能样机功能的划分和设计流程进行了分析。在对性能样机协同设计仿真业务进行需求分析的基础上,结合本体建模方法提出一种基于本体元模型的性能样机协同概念建模方法。以某超声速飞行器协同建模为例,给出性能样机协同概念建模案例,并采用Protégé工具构建了性能样机的本体元模型库,较好地解决了多学科产品模型的输出缺失和信息冗余问题,可以显式地表达领域知识并促进不同领域之间概念的语义一致性。
