Application of PHM Technology in Hydraulic Servo System |
| |
| Abstract: | To improve the reliability and availability of hydraulic servosystem, prognostics and health management (PHM) technology wasstudied and applied to the system. This paper focuses on fault detection, performance assessment and trend prediction technologies of hydraulic servo systemwhile its performance degradation occurring. The study of PHM technologyis the development direction of fault diagnosis technology and can provide strong theoretical support in the engineering practice for hydraulic servo system onfault detection, degradation assessment and life prediction methods.Finally, the experimental results are given in detail and prove the effectiveness and applicability ofthe PHM technologyin hydraulic servo system fault diagnosis. |
