摘　　要：研究了基于VMIC实时网络的分布式半实物仿真系统方案,对仿真系统的组成及仿真设备的功能进行了介绍。对比分析了仿真时钟生成的几种方法,选用Windows+RTX仿真时钟生成方法,在确保高精度仿真时钟的同时方便了仿真程序的开发。基于信息、事件驱动设计了仿真进程控制软件的总体结构。所设计的半实物仿真系统具有扩展性好、试验方式灵活的特点。The distributed hardware in the loop simulation system based on VMIC real-time network was studied, and the functions of various simulation devices were introduced. The Windows ＋ RTX generating a simulation clock method was selected to form several methods of generating a simulation clock. This method facilitates the development of the simulation program while ensuring the high precision of the simulation clock. Finally, the overall architecture of simulation control software was designed on the basis of message and events. This hardware in the loop simulation system possesses good expansibility and flexible test mode.
