摘　　要：提出一种基于FMEA的可靠性仿真分析技术,以降低FMEA验证试验的成本。将电子仿真技术和可靠性分析技术相结合,利用Saber仿真分析软件的FMEA/Testify工具,完成某型导弹舵面锁制系统故障模式及其影响分析。首先构建锁制系统的电路仿真模型,收集系统中所有电子元器件的常见故障模式,并进行故障注入,然后通过电路仿真技术,完成各故障模式对系统的影响评估、危害程度分析,辨识出影响系统可靠性的关键元器件。仿真结果表明,该分析方法具有较高的实用性,可以提高系统的可靠性分析水平。A reliability simulation analysis technique for FMEA to reduce cost of verification was proposed.Using a combination of reliability analysis and simulation technology,the FMEA/Testify simulation tool of the Saber software was used to analyze the failure mode and the effect of the locking system for the control surfaces of missile servo control system.The circuit simlation model for the locking system was constructed,and the failure modes of all the components were collected.Then all the failure modes were injected into the simulation model.After the execution of the simulation model,the failure model and the effect analysis results of the system were acquired.And the key components influncing the reliability of the system were identified.The results show that the analysis method of failure mode and the effect is practical and can improve the reliability analysis level.
