空空导弹冗余系统共模失效

Approach of Common Mode Failure Analysis in Redundant System of Air-to-Air Missile

为避免空空导弹冗余系统产生共模失效,提高产品可靠性和安全性。在研究共模失效分析方法的基础上,结合空空导弹的研制特点,对某型空空导弹电源组件点火电路冗余系统共模故障进行了定性分析,识别了点火电路中的共模故障,分析了故障原因和耦合因素,并提出了相应的改进措施。

In order to avoiding common mode failure of the air-to-air missile, and improving the reliability and safety of the product, combine the developing character of the air-to-air missile, made a qualitative a- nalysis of the common mode failure in the redundant system of a type air-to-air missile power supply module igniting circuit based on the study of the method of common mode failure analysis, identified the com- mon mode failure of the equipment, analyzed the cause of failure and the coupling factor, put forward improvement measures.
