一、重要性 故障分析是型号产品质量保证措施之一,国内外经验都证明了开展故障分析对保证产品质量确实有明显的作用。我厂生产的某型号产品,1984年定型批,在出厂的测试中多次出现了无线电高度表和引信烧保险的故障,为此,我们组织了专门的故障分析,并通过试验验证,最后找出烧保障的原因是设计参数选择和线路连接上的问题,通过修改设计,从而使产品顺利出厂进行飞行试验,试验结果证明采取的措施是正确的。××型号超期弹的延寿试验是一次大型地、系统地进行故障分折的工作,通过上百发弹的故障
First, the importance of failure analysis is one of the model product quality assurance measures, both at home and abroad have proved that the development of failure analysis to ensure product quality does have a clear role. Some models produced by our factory, in 1984, were typed and approved. In the factory test, there were several failures of radio altimeter and fuze burning insurance. For this reason, we organized a special fault analysis and verified it through experiments and finally found The reasons for the protection of burnout are the design parameters and the problem of line connection. By modifying the design, the product can be shipped out of the factory for flight tests. The test results prove that the measures taken are correct. The X-model model extended life test is a large-scale, systematic failure to break the work, through the failure of hundreds of missiles
