Degradation characteristics analysis is an effective and reliable method for life analysis of airborne hydraulic actuator. Compared with life data analysis, degradation score can usually provide more accurate evaluation results. In this paper, a certain type of airborne hydraulic actuator is taken as the research object. Based on the results of graphic analysis and distribution characteristics analysis, the degradation characteristics of performance parameters and rocker shaft clearance structure parameters are analyzed. The results show that the extrapolation method can be used to predict the product failure time based on the product performance degradation data, it can be used to quantitatively evaluate the performance degradation characteristics of actuators and provide useful support for the quantitative evaluation of actuator life.
