航天发射仿真训练系统中的分级建模技术研究

Research on Hierarchical Modeling Technologies in Spaceflight Launching Simulation and Training System

计算机仿真技术已广泛应用于各种仿真训练系统,针对训练系统中不同训练任务和训练过程以及场景对象运动控制等方面的建模是其中一个关键技术。结合航天发射仿真训练系统的实际建模需求和具体问题,从任务级、过程级和实体级3个层次分析了不同的建模要求,综合运用XML、UML、Creator、Vega、MATLAB等软件解决了训练系统的分级建模问题。应用结果表明,通过分级建模能够解决复杂仿真训练系统的建模问题,对一般仿真训练系统的研制具有一定参考意义。

Computer simulation technology is widely applied in varieties of simulation and training systems. This paper presented the three modeling technologies used in the spaceflight launching simulation and training system, such as system level modeling, procedure level modeling and entity level modeling. By different modeling requirements, the three modeling methods were analyzed and implemented. The experimental results demonstrate that the hierarchical modeling technologies can deal with the modeling problems in complex simulation and training system and act as a good reference to other develop- ment of similar software systems.
