基于故障数据的某型导弹失效风险排序方法
Method of Failure Risk Ranking of Missile Components Based on Fault Data
摘要
Abstract
In the background of the study on a certain type of missile, according to the professional, the missile was divided into eight subsystem, such as projectile, engine systems, electronic and electrical equipment, etc. Adopting FTA and FMMEA methods, the failure modes and mechanisms were analyzed. The severity level and occurrence probability level of failure modes were introduced to construct the failure mode risk assessment model, the failure hazardous degree of the missile's sub-systems was quantitatively analyzed. According to the missile site failure data during service and combined with prior information, and based on the Bayesian es-timation, the calculating method of occurrence probability level of each failure mode was put forward, the fail-ure sorting sequence of missile sub-systems was given and the weak links were determined, and providing sup-port for the subsequent prediction of storage life.关键词
