%X 基于相似产品历史数据和模糊理论，将频率综合器故障树各项定性参数进行量化描述。通过对频率综合器开展模糊故障树分析，求出了其常见故障模式本振输出信号异常的最小割集，全面梳理了以此为顶事件的各种可能底事件，对顶事件出现的可能性进行了预估，为设计优化、故障预判及防范提供参考。<br />
Based on the historical data of similar products and fuzzy theory, the qualitative parameters of the fault tree of the frequency synthesizer are quantitatively described. Through the fuzzy fault tree analysis of the frequency synthesizer, the minimum cut set of the abnormal local oscillator output signal of its common fault mode is obtained, various possible bottom events taking this as the top event are comprehensively combed, and the occurrence probability of the top event is calculated. The result provides a reference for product design improvement, fault accident investigation, analysis, prediction and prevention.
