电液伺服阀是伺服机构的一个关键元件,它的失效模式与其设计、生产以及使用环境直接相关。本文针对双喷嘴挡板式力反馈电液伺服阀进行FMEA,为伺服阀的设计、预防失效、故障诊断及可维修分析等提供依据。
Electro-hydraulic servo valve is a key component of the servo mechanism, its failure mode is directly related to its design, production and use of the environment. In this paper, FMEA is applied to the dual nozzle baffle force feedback electrohydraulic servo valve to provide the basis for the design of servo valve, failure prevention, fault diagnosis and maintainability analysis.
