In order to determine the influence of environmental sensitive stress in the actuator reliability enhancement test, improve product reliability, a certain type of actuator is taken as the research object in this work. From the perspective of environmental factors of fault modes, an environmental sensitive stress analysis method based on Analytic Hierarchy Process (AHP) is adopted to analyze nine environmental sensitive stress factors (including high temperature stress, low temperature stress, rapid temperature change stress, vibration stress, impact stress, acceleration stress, temperature height stress, damp heat stress and working load stress) of three inpatient fault modes, namely piston oil leakage, servo valve failure and plate valve failure. The influence weight of each environmental influence factor is obtained, and the results are consistent with the known empirical data of this type of actuator, which proves the effectiveness of the analysis method based on Analytic Hierarchy Process (AHP) for the environmental sensitive stress analysis of the actuator reliability enhancement test.
