针对高速列车耦合大系统的复杂多动态性和不确定性，本文提出一种本体驱动的高速铁路场景建模方法，构建可视化展示与仿真分析平台。根据耦合仿真的建模需求构建完备基元模型库，并用地理本体对模型的空间关系进行语义描述，制定语义约束规则对建模过程加以约束和引导，生成高速铁路场景。在虚拟场景中，通过控制观察视角与列车运行速度，即可开展多视角、多运行状态的模拟仿真。案例实验表明，本文构建的基元模型库精准、完备，基于本体描述的基元模型间语义信息，能够有效支持动态耦合仿真过程中各子系统间复杂动态空间关系的分析。研究成果能够为高速列车耦合仿真提供建模服务。

Considering the complex dynamic properties and the uncertainties in high‐speed trains during the gen‐eral coupling simulation process , this paper proposed an ontology‐driven method of creating high‐speed railway scenes to construct a platform for the visual display and analysis of simulation data . A complete basic element model base was built in relation to the modeling requirements of coupling simulation .Meanwhile ,a semantic description of the spatial relationships among the models was given by using geo‐ontology modeling methods . Then various semantic constraint rules were developed to control and guide the modeling process , to dynami‐cally generate a high‐speed railway scene .In this virtual scene ,a simulation of multiple perspectives and run‐ning states w as conducted by means of controlling the perspectives of observation and the running states of a train . The experiments showed that the basic element model base presented in this paper is accurate and com‐plete , and the geo‐ontology described semantic information effectively supported the analysis on complex and dynamic spatial relationships among subsystems during the dynamic coupling simulation process . The research results can provide modeling services for the coupling simulation of high‐speed trains .
