摘要
研究在故障实时诊断的基础上在线排除滑阀机构卡紧故障的方法。提出了“电击锤”的概念,它体现了一种利用电磁力在线自动排除卡紧故障的新思路;给出了应用实例——带故障检测、容错运行和故障在线排除功能的动力控制系统电液执行机构,可提高液压系统的运行可靠性。
A new method of on line removing a spool sticking is discussed. The method is based on some real-time fault diagnosis technologies which are also introduced in the paper. 'Electrical hammer' a new concept of sticking trouble removal using an electromagnetic force is presented. An application example, that is an electro-hydraulic actuator of power control system with the functions of fault diagnosis, fault-tolerance and trouble removal is given. The research results of the paper are helpful to enhance operating reliability of hydraulic system.
