摘要：
Electro-hydraulic servo valve is the key component in electro-hydraulic servo control system, it has high reliable assemblies over a long period of time. This paper utilizes the accelerated degradation testing to evaluate their reliability and life. Firstly, the wear failure mechanism of electro-hydraulic servo valve is analyzed to determine. Then, by modeling the degradation process as a drift Brown Motion, this paper generated the reliability model of the electro-hydraulic servo valve. Finally, the maximum likelihood is used to estimate the degradation data of leakage from the test. The methodology in this paper is demonstrated and validated by reasonability of estimation of electro-hydraulic servo valve.
