摘　　要：余度数字阀具有可靠性高的优点,是未来数字阀的一个重要发展方向。数字阀可靠性的薄弱环节一般为其驱动机构,针对该情况,该研究提出了一种采用主备式驱动机构的双余度数字阀方案,介绍了其组成和原理,对其动静态性能进行了理论研究,并进行了仿真分析和相应的试验验证,最终给出了结论。Redundant digital servo valve is an important direction for future development of the digital servo because of its high reliability.Commonly, the drive mechanism is considered to be the weak part of the digital servo valve.Given this, the study presents a redundant digital servo valve with a primary and a stand By drive mechanism. Firstly, the composition and the principles are introduced,then theory and simulation analysis, as well as the experiments are carried out.Finally the conclusion is given.
