摘　　要：针对机载维护系统的仿真验证需求,提出了一种仿真激励环境的设计方法。通过辅助开发工具集定义故障模式,配置设备维护参数。利用成员系统仿真器软件管理仿真数据,采取轮叫调度频率控制方式完成多种设备、多种总线、不同频率和类型的仿真数据发送。利用该系统可以克服以往单一设备故障注入方式的弊端,实现支持复杂故障模式、大量动态飞行参数、启动测试数据和数据加载功能同时验证的多样化、综合化功能仿真,满足机载维护系统对成员系统的动态功能行为和静态分析数据的功能要求,提升了机载维护系统应用的开发进度。According to the requirements of verification of onboard maintenance system(OMS),a design method of simulated excitation environments is proposed.The fault modes were defined and the equipment parameters were configured through the auxiliary development toolset.The software of the member system simulator was used to manage the data,the round-robin scheduling control mode was adopted to complete the simulation data transmission of various equipments,multiple buses,different frequencies and types.The environments can overcome the disadvantages of the previous single device fault injection mode,and realize the diversified and integrated function simulation of complex fault modes,a large number of dynamic parameters,startup test data and data loading function at the same time.It meets the requirements of the OMS for the dynamic functional behavior of the member system and the static analysis data,and improves the development progress of the OMS applications.
