新型直接驱动伺服阀的瞬态液动力分析

Analysis of transient flow force in a new direct drive servo valve

本文设计了一种采用转动式阀芯的直接驱动伺服阀，推导了这种阀在工作时阀芯所受到的瞬态液动力的数学表达式，得出了一些有用的结论，对高性能直接驱动伺服阀的研制具有很好的指导作用。

This paper designs a direct drive servo valve with rotary spool, derives a mathematical expression of transient flow force of the spool in the valve, and obtains some useful conclusions, with having very good instructiveness for developing the high-performance direct drive servo valve.
