Fatigue Scatter Factor of Whole Life and Reliability of AircraftStructure Service Life

摘要：

The prediction of aircraft structure service life is of great importance to safety of aircraftstructure and human beings.The relation between aircraft structure service life and reliability canbe found by utilizing the fatigue scatter factor of whole life.Only when the service life satisfies therequirements of reliability,can the safety of airplane be ensured.The fatigue scatter factors of theservice life accords with lognormal distribution and Weibull distribution were studied to provideimportant reference for predicting the safe service life of aircraft structure.

关键词： Aircraft structure service life Fatigue scatter factor of whole life Reliability Lognormaldistribution Weibull distribution
