| Abstract: | To improve functional reliability of hydraulic system of missile launch vehicle, fault mode of hydrau- lic system was analyzed according to three hierarchical structure. Set hydraulic system as an exemple, method for classifying and processing of monitoring signal were analyzed, and health evaluation method based on the health degree was studied. Health degree was used to quantitative evaluation health condition of hydraulic system. And fault diagnosis and locating by fault tree was studied for non-health condition. |
