摘要
应用故障树分析法,对某型雷达发射机故障树进行了分析,得出导致发射机不能正常工作的概率,然后对每个底事件的概率重要度进行了分析.设计人员在设计过程中会根据此分析对底事件加以重视,这样发射机的可靠性和安全性在设计阶段就会得到本质上的提高。
Appliing analysis method of failure tree,the article analyzes the fault tree of certain radar transmitter,and educes the probability that leads to abnormal operation of the transmitter,then analyzes the importance degree of each basic event. According to the analysis,the designer will focuse these basic events during the design process, thus the reliability and safety of the transmitter will be improved essentially in design phase.
