SYSTEM AND METHOD FOR HEALTH MONITORING OF HYDRAULIC SYSTEMS |
摘要 |
A method of health monitoring of a hydraulic system includes measuring a hydraulic fluid level at a first location in the hydraulic systems and measuring one or more of hydraulic fluid pressure and hydraulic fluid temperature at one or more second locations in the hydraulic system. A snapshot of data is identified that meets a mode detection criteria a model requires to estimate the hydraulic fluid level. An expected hydraulic fluid level is calculated based on the measurements of hydraulic fluid pressure and/or hydraulic fluid temperature, and the expected hydraulic fluid level is compared to the measured hydraulic fluid level, the difference an indicator of leakage in the hydraulic system. |
