使用GO法对航空活塞发动机点火系统成功概率进行分析,建立GO图并确立操作符的类型和故障概率,并分别使用定量和定型分析方法计算点火系统的成功概率。通过验证,可知点火系统有共有信号修正的数学模型的可靠性精度比较高,适用于点火系统可靠性分析。 The GO method is used to analyze the success probability of the aircraft piston ignition system, the GO diagram is established, the operator type and the failure probability are established, and the success probability of the ignition system is calculated respectively by using quantitative and qualitative analysis methods. Through the verification, it can be seen that the reliability of the mathematical model with common signal correction in the ignition system is relatively high, which is suitable for the reliability analysis of the ignition system.
