随着现代控制技术的发展,越来越多的大吨位强度、疲劳试验设备,如振动台,疲劳试验机等均采用电液伺服控制系统。而在这类系统中,采用什么样的电液转换元件,是一个十分重要的问题。本文介绍了航空工业部三O三所研制的DySF-3G型三级电液伺服阀的结构特点、工作原理、技术指标以及使用实例。并较为详细地介绍了试验的数据,可供参考。文中图10幅表3个。
With the development of modern control technology, more and more large-tonnage strength, fatigue test equipment, such as shaker, fatigue testing machines are used electro-hydraulic servo control system. In such systems, what kind of electro-hydraulic conversion element, is a very important issue. This paper introduces the structural features, working principle, technical indicators and application examples of the DySF-3G three-stage electro-hydraulic servo valve developed by the Ministry of Aviation Industry. And a more detailed description of the experimental data for reference. Figure 10 table 3.
