摘要
通过分析比较各级各类与Ⅰ、Ⅱ类单点故障模式有关的质量管控文件要求,在各型号开展Ⅰ、Ⅱ类单点故障模式识别及质量控制工作的基础上,对Ⅰ、Ⅱ类单点故障模式的识别方法现状进行了分析,提出了基于FMEA和FTA识别型号的Ⅰ、Ⅱ类单点故障模式;同时从关键特性分析与控制、强制检验点设置与控制及“不可检、不可测”产品识别与控制3类方法对Ⅰ、Ⅱ类单点故障模式的质量控制方法进行了总结,并提出了适应性改进,使不同级要求合并,形成最大包络要求,然后保证同一要求在不同型号开展过程中理解到位、思想统一等。
Through analysis and comparison of relevant quality management and control documents’requirements of all levels with TypeⅠandⅡsingle point of failure modes,on the basis of each task’s TypeⅠandⅡsingle point of failure modes’recognition and quality control,the situation of TypeⅠandⅡsingle point of failure modes recognition method is analyzed,based on FMEA and FTA,we propose a“double F”method,namely FMEA and FTA model’s TypeⅠandⅡsingle point of failure modes.Meanwhile,we use three types of ways to summarize TypeⅠandⅡsingle point of failure modes’quality control methods.The Three ways are key characteristic control,mandatory inspection point setting and control,‘Unexaminable,Untestable’product recognition and control.Then adaptive change is requested.Different levels must be merged in order to meet requirement of maximum envelope.For these requirements,everyone should have correct understanding and share same thoughts during Long March Rocket series missions.
