| Abstract: | In this paper, the plunger - type variables aviation hydraulic pump of aircraft is researched firstly, the failure mode, failure cause and degradation parameters of the aircraft hydraulic pump are discussed, then the accelerated degradation model is built, and the accelerated degradation test plan is determined. Based on the degradation data from the accelerated degradation test, the reliability evaluation procedures are developed. Finally, the accelerated degradation test data from some aircraft hydraulic pumps is studied as an example, and the reliability of the pump is analyzed, the analysis results give the predicted reliability variation over time. |
