摘　　要：针对卫星静态仿真方法未实现故障时序发展过程及影响范围仿真的问题,在故障仿真方法进行分析的基础上,提出了一种基于层次模型的动态故障仿真方法,即通过建立不同层级的故障模型,利用动态仿真推进方法实现故障的时序发展过程仿真。此方法能够有效提高故障仿真的精细化程度,为故障处置提供支撑。通过某卫星能源安全模式故障仿真,对方法的有效性进行了验证,结果表明该方法能够满足故障仿真要求,可为卫星故障仿真系统设计提供参考。As the satellite static simulation method can not realize the simulation of fault time sequence development process and influence range,a dynamic fault simulation method based on hierarchical model on the base of analysis of fault simulation method is presented,that is by establishing fault models at different levels,the dynamic simulation propulsion method is used to realize the simulation of fault time sequence development process.This method can effectively improve the refined degree of fault simulation and can provide support for trouble shooting,the effectiveness of the method is verified by the fault simulation of certain satellite resource in safety mode.The results show that the method can meet the requirements of fault simulation and can provide the reference for the design of the satellite fault simulation system.
