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...
When the vehicle parks in the hot environment, the temperature inside the cabin would increase substantially, and has a bad impact on the comfort of occupants. Ventilation is an effective cooling means in hot environment and the current method applied in vehicle is apt to open ventilation system transitorily when the car starts, reaching the pre-cooling purpose. However, the working hours of ventilation...
According to the failure characteristic of aircraft structure, the delay-time model is an effective method to optimize maintenance activities of aircraft structure to decrease maintenance cost rate. In order to be consistent with the actual situation as much as possible, imperfect inspections, threshold and repeated intervals are been considered in the delay-time model. What's more, the all exsiting...
