摘　　要：作为一种混合系统,鱼雷是连续系统和离散系统的结合体。而鱼雷仿真贯穿于包括需求分析、设计、效能评估、模拟训练的全生命周期。针对以往仿真开发过程中缺乏共同认可的知识,提出了一种改进的混合DEVS形式化建模方法并定义了混合原子模型和混合耦合模型,在此基础上给出了鱼雷各原子模型和耦合模型的描述。构建了基于混合DEVS的鱼雷仿真本体,其顶层实体包括仿真对象、仿真序列、仿真算法、模型类、函数、参数、时间、状态、事件和仿真记录。以空投鱼雷为例,通过参照鱼雷仿真本体改造了传统的仿真模型。仿真结果表明所建立的本体能有效表示鱼雷仿真领域知识和正确指导其模型开发。As a kind of hybrid system, torpedoes are combination of discrete and continuous subsystems. From requirements analysis to design, from assessing performance to training simulators, simulation is employed throughout the whole life cycle. It is a common practice that these simulations lack of the same understanding of knowledge. A modified approach Hybrid Discrete EVent System Specification（HDEVS） formalism was proposed by giving the definition of hybrid atomic model and coupled model. The description of torpedo under this method was given. Moreover, corresponding ontology, HDEVS-based Torpedo Simulation Ontology（dubbed HDTSO）, was constructed of which the top level entities are simulation object, Simulation Sequence, simulation algorithm, model class, simulation function, parameter set, time set, state set, event set and simulation record. Taking aerial torpedo as an example, traditional simulation models were improved with help of the proposed ontology. As a result, domain knowledge was represented by HDTSO which could guide relevant model development.
