在收集已发生故障数量和故障模式的基础上,应用故障树分析的原理,对某型照射器建立故障树模型和最小割集分析,根据计算概率重要度,确定照射器的质量改进内容。
Based on the collection of the number of failures and the failure modes, the fault tree model and the minimum cut set analysis of a certain type of illuminator are established based on the principle of fault tree analysis. According to the calculation of probability importance, the quality improvement of illuminators is determined.
