摘　　要：为满足火箭炮精确维修保障的要求,提出一种基于FMEA和模糊贴进度的火箭炮故障维修方式选择方法。该方法在传统FMEA基础上引入模糊理论,对故障风险指标进行模糊评价,并建立不同维修方式对应的标准故障模型。然后比较火箭炮故障与标准故障的综合贴进度大小确定最合理的故障维修方式。最后,以火箭炮火控计算机为例验证该方法的可行性。结果分析显示,该方法降低了评定难度,结果更加合理准确,能够满足火箭炮维修保障实际需要。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.
