摘要：Aiming at the accurate prediction of APU residual life in civil aviation, Fusion of historical state performance monitoring data, a method of APU residual life prediction based on proportional hazards model (PHM) is proposed. This method first gives a life prediction algorithm based on PHM. Then, based on the historical performance degradation data and historical failure time data, the genetic parameters are estimated by genetic algorithm. So as to obtain the remaining life of aviation APU distribution, and ultimately to achieve the remaining life expectancy of aviation APU. The experimental results show that the method has high prediction accuracy and can provide the basis for the development of aviation APU maintenance plan.
