Study on the application of improved FMEA in the choice of fault maintenance mode of rocket gun
Year: 2025
Type: article
Abstract: To meet the precise maintenance support requirements of rocket guns, a method for selecting fault repair strategies based on FMEA and fuzzy closeness is proposed. This approach enhances traditional FMEA by incorporating fuzzy theory to evaluate fault risk indicators, and establishes standard fault models corresponding to different repair strategies. The most suitable repair method is then determined by comparing the comprehensive closeness between the rocket gun faults and the standard fault models. The method's feasibility is demonstrated through a case study involving a rocket gun's fire control computer. The analysis reveals that this approach simplifies the evaluation process, delivers more reasonable and accurate results, and effectively meets the practical demands of rocket gun maintenance support.
