Failure mode and effect analysis of locking system for control surfaces of missile servo control system

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.
