摘　　要：近年来武器平台级仿真除用于训练外,也逐步应用于武器装备试验评估领域。平台级仿真包含实体数多、交互信息复杂;如果有人或硬件在回路,则需实时运行;如果采用分布式结构,还需时间同步。为了解决帧速率不同的实体间复杂信息交互、实时运行和时间同步控制等问题,参照HLA的时间机制设计了平台级仿真中多帧速混合时间推进方法,并采用流行的Windows+RTX平台开发了某武器平台分布式实时仿真系统。该设计方法适用于多实体交互、强实时推进和时间严格同步的武器平台级仿真系统构建。Platform-level simulation has applied to weapon equipment test and evaluation besides training. It contains a large of entities and intricate interactions. The system must run in real-time if it is the human-in-loop or hardware-in-loop system. Furthermore, the system must be synchronized if it is distributed. To solve the problem of intricate interactions, strong-real-time running and clock synchronization controlling between entities with different frame-rate, the paper designed the time advance mechanism by reference to time-management mechanism in HLA, and developed the simulation system based on Windows ＋ RTX platform. The design in this paper can be used to construct platform- level, multi-entities interaction, strong-real-time distributed simulation systems.
